Deciding when to have the talk about where babies come from can prove to be tricky — for oh so many reasons.

Adding the conversation of surrogacy as one of the different routes to parenthood can pose an additional challenge for parents who aren’t sure what their child is ready for when it comes to learning about pregnancy and childbirth.

There isn’t a hard-and-fast rule on when you should start to talk about surrogacy with your kids, and as such, many parents opt to wait until their kids start asking questions — just like with questions about pregnancy and reproduction in general.

But many psychologists recommend being open and honest about the surrogacy process from the get-go, whether that includes explaining it to a child who was conceived via surrogacy, or if your child is watching you serve as a surrogate.

“Having a baby is an exciting time for any parent-to-be. There are many ways to have a baby today, including more families using a surrogate to achieve parenthood,” says Roseann Capanna-Hodge, EdD, a licensed professional counselor and certified school psychologist in Ridgefield, Connecticut.

“Parents should always try to include their children in the process as much as possible and consider developmental age,” she adds.

A smaller study from 2013 suggests that keeping a child’s surrogacy story a secret can prove to have negative impacts, as it can lead to feelings of shame and distrust as kids grapple with their sense of identity.

“No matter how a new sibling arrives, a new baby in the house can bring a range of emotions, including excitement and jealousy,” Capanna-Hodge says. “Finding ways to connect with this new baby is critical in building great communication and establishing a bond, as well as helping the other children feel secure.”

Fortunately there are a number of resources that can break it down for kids in a fun, respectful, and easy-to-understand way.

“Using books and making art to help the child understand that someone else is helping the baby ‘grow in their belly (or uterus)’ will also help the child gain an understanding that the baby is coming,” Capanna-Hodge says.

“Ultimately, when you feel good about what you are telling your child, they will not only accept it but they will feel good, too,” she says.
