Acer back in the orphanage?

I just found out from another mother to be (out of the same waiting child batch and the same province as Acer) that she heard they will take Acer (and her Hannah) away from the foster families they've been with and put them in the orphanage before we come get them. She says it's so they bond better with us, but I hate to think of the little guy pulled out of his foster family and put into a situation where they don't really know him. No sad little guys! He'll be all confused and lonely for so long until we get there.
