If this is an inappropriate question, please let me know and I will delete this post entirely. But if the child is one and he's already been in foster care for a year, that means probably from pretty early infancy. We know babies bond at an early age. May I ask why they would move a toddler that has already bonded with another family? Is the purpose to keep the child from attaching too much to any one couple so that they can someday be reunited with their birth parent? I've never understood this. I'd like to know the reasoning. But as I said, this question may be inappropriate and I do understand that you may not want to or be able to answer.
I don't know the specific reason why snowflake's little one was moved, but I have seen this happen. Generally it is not to keep the child from attaching too much. That may have been the reason in years past but nowadays (Thank God!) the system seems to be a little smarter about infant/child attachment. When we were fostering (closed since adopting a year ago, may reopen soon!), we were what is known as a "concurrent" home. Meaning, we would get placed with children on the basis that if reunification wasn't successful, we were already approved and willing to adopt if necessary. At least in my state, most really little ones are placed in concurrent homes unless it's strongly suspected they'll be going back to their birth families.
I know of a family who had a sibling group for about a year, then the mother was diagnosed with a usually fatal form of cancer. They did move the sibling group (after a transition period).. heartbreaking.
Another family that I know had a newborn for four months. The grandmother then got permanent custody of her, and she was with gma for three months, when gma decided that it was too much. In that time, the original family had taken placement of a group of three older children that had varying issues.. developmental delays and emotional issues. It wasn't a safe situation for the now-7 month old to return to, so they placed her in another foster home.
There are a lot of things that can happen to cause a child to be moved, even the little ones.
