Can I refuse to see my brother's baby?
Do you have an issue with your brother or the baby?
Yes, I don't like this kid. It's very ugly and I do not want to be more invested into this ugly creature
That's not right not wanting to see the child because of the way it looks. You shouldn't avoid your niece or nephew because you find them physically unappealing.
The kid exploded this morning for no reason.
Babies are not supposed to be easy. You need to be patient and realize they get easier and they get cuter too.
