I feel like everybody is playing me as the crazy one lol

My baby does GREAT with other kids, we try to take him out every weekend so he can be around others.

Now when he sees my bfs family, which is like 1 time a month, he starts crying and doesn’t want to go to them. He’s 16 months old and I tell her his behavior is normal, since they’re practically strangers .. but she starts belittling him saying “it’s not normal, he’s a crybaby” “he needs to be in day care around other kids” “he’s not even talking” etc etc.

I’m like what???? I feel like maybe she should apply herself more as a grandma so that he can get to know her & maybe he won’t cry anymore
