I am in a position to adopt a little boy (age 4) that I love, and who loves me a lot. He is doing okay in their home, but there is a lot of stress, and competition with their son of a similar age. My son is older, and loves the little boy also. Anyway, he has a younger sister (age 1) that is very, very attached to my friend. My friend doesn't feel that she can parent the boy, but also feels that she shouldn't let the sister go. They are foster parents. My friend and I are very close, like sisters, and see each other often, even when we lived in different states, so the kids will get to see each other. Not daily, or at times, even weekly, but lots.
Is it a really bad idea to separate them even if it seems in their best interest?
