I heard on one of the afternoon radio shows that Rosie's giving the kid back because the kid keeps hiding food from her probably because she's afraid she'll starve in Rosie's household.
On a second note, isn't Rosie the picture of compassion? Hey, she loves to adopt and keep kids when they are easy to deal with but when she gets one that has a problem or two, she wants to send them back as defective. B^%$@!!!
