You haven't the ability to think, let alone rethink. Given the rest of your post, that is about a 6 year old girl, not a baby.
Do I really have to explain the difference between a child and an infant? Or is this your way of skirting around facts, so you don't have to acknowledge reality?
Completely irrelevant.... They're unwanted ... As well, the adoption process takes a long time, you aren't likely to adopt an infant immediately after birth.
