How do you not worry about them so much?
My daughter LOVES her baby brother, but me she's not so crazy about most of the time. She's giving me Hell all day long, and rejecting my affections. Maybe I'm over-doing it in an attempt to convince myself that things are the same as before between us. They clearly are not. This will pass, I'm sure, but in the meantime I'm just so hurt.
Maybe she is too.
