So, you are asking about people giving up their baby for adoption right? Not the people doing the adopting?
I think it is almost always extremely difficult to give up a baby. I think sometimes it is completely selfless, but also sometimes the woman or girl or parents see the baby as an obstacle to their own desires in their own future.
I don’t think every time a 16 year old gives up a baby it’s wholly because she wants a better life for the baby. It’s a mixture of reasons and emotions.
I don’t know how people do it. I can’t imagine it. It has to be heart wrenching in a way hard to imagine unless you have been through it. I would go insane not knowing how my child is every day.
