I have been a daddy to adult Baby Girls for 15 years now. I prefer those who missed out on their childhood due to abuse because this is an area I am all to familiar with. I am just a daddy to these girls, not a partner. The Baby play is a way for them to learn trust and to deal with the past abuse. They need to experience a relationship where everything is centered around their needs and well being without any expectations of reciprocity.... except maybe Hugs or 'fridge art !!
Honestly,, I benefit from these relationships too. Whenever you can take something bad in your life and use it to help others, then it's no longer an obstacle.
Sorry for the "lurking", It helps for people to read that others have gone through similar experiences. As youngsters, we tend to blame ourselves for the things that happen. Sites like this help people to understand we aren't alone.
