Platonic Parenting: What Is It and How Does It Work?

Platonic parenting is when two or more people decide to raise a child together without being in a romantic relationship — from conception onward. Also known as elective co-parenting or intentional co-parenting, this family model is growing rapidly across the United States and beyond. Whether you are a single person, part of a same-sex couple, or simply someone who wants to share the joys and responsibilities of parenthood with a trusted partner, platonic parenting offers a deliberate, stable path to building a family on your own terms.

Understanding what platonic parenting involves, why it’s on the rise, and how to get started can help you decide if this family model is right for you.

What is platonic parenting?

Platonic parenting is a family arrangement where two or more adults agree to conceive and raise a child together while maintaining a purely non-romantic relationship. Unlike co-parenting after divorce — where former romantic partners share custody of existing children — platonic parenting is an intentional choice made before the child is even conceived.

The co-parents in a platonic parenting arrangement function as a team. They share all responsibilities and rights towards their child. Any important decisions related to the child — educational, medical, spiritual, financial — are taken jointly. Some platonic co-parents choose to live under the same roof, while most live in separate homes and share custody, typically staying close to each other geographically. This collaborative, conflict-free approach is what makes this family model a stable and intentional way to build a family.

Platonic parenting may also concern those who are divorced or separated but have decided to stay together to raise their children cooperatively. However, the term is most commonly used for people who choose to co-parent a child without being in a relationship from the very beginning.

Why are more people choosing platonic parenting?

Several demographic and social shifts explain why this approach to family building is growing in popularity.

First, people are having children later in life. According to the CDC’s National Vital Statistics Report (2025), the mean age of first-time mothers in the United States reached 27.5 years in 2023, up from 24.9 in 2000. First births among women aged 35 and older increased by 25% between 2016 and 2023. Many women who haven’t found a romantic partner but feel their biological clock ticking are now exploring alternatives to single parenthood.

Second, family structures in the U.S. are evolving. About 40% of all births in 2023 were to unmarried women, according to CDC final birth data. Meanwhile, 42% of American adults now live without a spouse or partner. Marriage rates continue to decline, and more people are redefining what family looks like.

Third, the emotional and financial toll of divorce weighs on many prospective parents. Those who have experienced the divorce of their own parents are often concerned that starting a family with a romantic partner could end in a difficult separation — one they know will be hard on the child. Platonic parenting offers an alternative: by remaining friends rather than being in love, co-parents can avoid many of the issues tied to a romantic breakup. Respecting and supporting each other comes more naturally, and as a result, the wellbeing of the child is more easily protected.

Additionally, this co-parenting model removes the emotional complications of romantic expectations. Co-parents can focus entirely on their shared goal — raising a happy, healthy child — without the ups and downs of a love relationship interfering with parenting decisions. Dedicated platforms have seen rapid growth: Modamily, one of the leading co-parenting apps, grew from roughly 30,000 registered users six years ago to 100,000 by 2025.

Why raise a child with a platonic partner instead of using a sperm donor?

Having a child alone is one solution for those who don’t want to give up on their dream of starting a family. To become pregnant, they can choose to look for a sperm donor, whether known or anonymous, through online platforms or a sperm bank.

However, many women prefer to explore this co-parenting model rather than using a sperm donor who won’t be involved in their child’s life. With a platonic partner, the child grows up with two actively engaged parents who share custody, financial responsibilities, and day-to-day caregiving. Research from the American Society for Reproductive Medicine (ASRM) consistently emphasizes that children benefit from having stable, involved caregivers — regardless of the parents’ romantic status.

Lesbian or gay couples can also choose platonic parenting by partnering with a single man or woman, or with another couple who are willing to have a child through a co-parenting arrangement. This is often seen as a more accessible and affordable alternative to surrogacy.

How to find a platonic parenting partner

If you want to explore this path to parenthood, one solution is to discuss with those around you your wish to start a family without being in a relationship. You may have friends — single or otherwise, heterosexual or homosexual — who are also looking for someone to have a baby with.

Those who don’t know anyone willing to raise a child with them, or who don’t feel comfortable discussing the idea within their social circle, can look for a platonic partner online using a dedicated website. CoParents.com — a co-parenting and sperm donation platform established in 2008 with over 150,000 members — connects men and women wishing to start a family through platonic parenting via a large and active database of profiles.

Once they have found their potential partner, the two parties can agree on a platonic parenting agreement that clearly defines the roles, responsibilities, and expectations of each co-parent. It is strongly recommended to put this agreement in writing and, where possible, to seek legal advice to protect the rights of both parents and the child.

How to choose the right platonic parenting partner

Taking the time to find the right co-parent match online is essential, as you will become partners for life once your baby is born. The success of any co-parenting arrangement depends largely on the strength of the relationship between the co-parents.

Keep in mind that the search for the right person can sometimes last for months or even years. Before committing to each other and going any further, you need to be certain that you are on the same page regarding parenting values, lifestyle, discipline, education, religion, and finances. It’s important that you take the time to get to know them very well, in order to be perfectly sure that you can trust them.

Key topics to discuss before entering a platonic parenting partnership include: where each parent will live, how custody will be shared, how expenses will be divided, what happens if one parent wants to relocate, and how decisions about the child’s health and education will be made. Family therapists and co-parenting coaches recommend discussing these issues early and in detail — ideally before any legal or medical steps are taken.

How to conceive with a platonic parenting partner

There are different ways to become pregnant when starting a family through this arrangement. One option is to undergo artificial insemination. The process involves collecting and then inserting the sperm of the male co-parent into the woman’s uterus or cervix. This procedure can be performed at home with an insemination kit or in a fertility center by medical staff.

Another option is natural insemination through sexual intercourse. If this is your choice, make sure that your co-parent has undergone all of the necessary medical screening tests, including HIV, hepatitis B and C, chlamydia, gonorrhoea, and syphilis. The American College of Obstetricians and Gynecologists (ACOG) recommends comprehensive STI screening before any conception attempt with a known partner.

In vitro fertilization (IVF) is an alternative for those who have fertility issues — for instance, blocked or damaged fallopian tubes, ovulation disorders, or premature ovarian failure. IVF is also a solution for those who require donated eggs. According to the CDC, approximately 2.3% of all U.S. births each year involve assisted reproductive technology. To perform IVF, the woman’s eggs (or those of a donor) are fertilized by sperm in a laboratory, and the resulting embryo is then transplanted into the woman’s womb. IVF costs in the U.S. typically range from $15,000 to $30,000 per cycle, depending on the clinic and specific treatments needed.

Whichever conception method you choose, this approach gives you the freedom to focus on finding the right partner and the right approach to building your family — on your own terms.

Legal considerations for platonic parenting in the United States

Legal recognition of this family model varies significantly by state. In most states, both biological parents have legal rights and obligations regardless of their romantic status. However, for non-biological co-parents — such as the partner of a woman who carried the child — establishing parental rights often requires additional legal steps, including second-parent adoption.

A co-parenting agreement should be drafted before conception, ideally with the help of a family law attorney. This document should cover parental rights and responsibilities, custody schedules, financial contributions, medical decision-making authority, plans for relocation, and how disputes will be resolved. While co-parenting agreements may not be legally binding in every jurisdiction, courts generally consider them when making custody determinations.

Some states, including California, Delaware, Pennsylvania, Oregon, and Washington, now recognize multi-parent families, which can be particularly relevant for same-sex couples entering a platonic co-parenting arrangement. Estate planning — including wills and beneficiary designations — should also be updated to include your child.

Frequently Asked Questions

What is the difference between platonic parenting and co-parenting after divorce?

Platonic parenting refers specifically to a deliberate choice to raise a child with someone you are not romantically involved with — often from the point of conception. Co-parenting after divorce occurs when a formerly romantic couple separates but continues to share parenting responsibilities. While both involve collaboration, platonic parenting is an intentional family model built from the start without romantic expectations.

Is platonic parenting legally recognized in the United States?

Legal recognition of this family arrangement varies by state. In many states, both biological parents have legal rights regardless of their romantic status. However, it is strongly recommended to draft a co-parenting agreement and consult a family lawyer to establish parental rights, custody arrangements, and financial responsibilities before the child is born. Some states now allow three or more legal parents on a birth certificate.

How do I find a platonic parenting partner?

You can start by discussing your plans with friends and family. If you prefer a wider search, dedicated platforms like CoParents.com — a co-parenting and sperm donation platform with over 150,000 members since 2008 — connect individuals who are looking for a platonic parenting partner. Take time to get to know potential co-parents thoroughly before making any commitments.

Can same-sex couples use platonic parenting to start a family?

Yes. This family model is a popular option for same-sex couples who want their child to have a relationship with both a mother and a father figure. A lesbian couple might partner with a single man, or a gay couple might partner with a woman willing to carry and co-raise the child. In 2018, a Canadian court issued a landmark ruling granting equal parental rights to two platonic co-parents who were not romantically involved.

What should a platonic parenting agreement include?

A comprehensive platonic parenting agreement should cover each parent’s rights and responsibilities, financial arrangements, custody schedules, living arrangements, medical decision-making authority, religious and educational preferences, plans in case of relocation, and a process for resolving disputes. It is best to draft this document with the help of a family law attorney before conception.
