Quoting Mrs. Mommy to 6 ღ 35:" change your avi please.. i get frightened every time you post."
That was mean. I didn't think she deserved that at all by what she said.
However, the changes probably are a lot for the little guy to handle. I don't know the entire story, but if he's being bounce from one place to the other....that's rough. Be consistent, remind him how important it is to share, don't hesitate to stick him in timeout if needed....but show some grace. Sounds like the little guy is having a hard time with whatever adjustments he's having to make.
