If you adopt ethically, there is little possibility of that. If you are seeking a just born infant, then yes, some mothers do decide that they do not want to adopt out their child upon delivery. If you adopt through foster care, then you would be able to choose your 'risk level'. Some children will already have their parents' rights terminated. These children range in age, but most will be older--at least toddlers--since in most states the natural parents are given at least 15 months to correct the problems in their home. If you so choose, you can request that any child you take in already has their parents' rights terminated. Expect that, again, this child will be at least a toddler AND that you will wait a little longer, as there are many adoptive parents that choose this route and not a whole lot of children in the system who already have been released legally from both parents. Foster care adoption ONLY takes place when there is a HIGH probability that the parents will not change their home life/behavior, or they have done something that cannot be 'fixed' andthe child would be in danger by living in that home. Once a child has been referred to the adoption section of foster care, it is VERY likely that they will not be returned to their natural parents....but it is always a small risk....the parent could suddenly get on board. There is a term for the few parents who do this...suddenly getting involved when the child is up for adoption/termination of rights. Generally, this is a short lived effort on their part, but a small few do genuinely change for the better.
Foster care adoption is free or nearly free, and once you adopt....once the parents rights are terminated, no, they cannot get their child back. Someone mentioned 'closed adoption' in their answer. That has NOTHING to do with rights to a child. Open adoption is always better for the child--if there has been no abuse. Closed adoptions simply mean that you share no pictures, updates, or any other mention with the natural parents. I HIGHLYsuggest that you always strive for an open adoption.
