After five weeks of being with the kid, he is developing normally. He eats, sleeps and burps like any month old. I imagine he could urinate for Canada, but I may be skewed in my perception. He occasionally smiles. He has wrapped us all around his finger. Younger has worried she may be getting ignored, but I have worked on that with her, and she seems better now. She loves her little brother, as does elder. All is well.
