Opinions please...

My 16 month old father and I have been pretty rocky since my son was born and long story short he lives with his uncle right now. He has a 10 year old son as well and he treats them COMPLETELY different. Always yelling at our one year old calling him a pain in his ass and annoying. While the 10 year old can get away with ANYTHING. He acts like he doesn’t want us around when he has his 10 year old. He’s always wanting me to come over and watch football but today he has his other son and basically said I can’t come watch football because he doesn’t want to piss off his uncle. Every other time he BEGS me to come. He thinks our one year old is annoying so he doesn’t want us there but his 10 year old runs around and plays ball inside all day. Am I overreacting? He also refuses to tell him I’m pregnant again. He didn’t let me come around his son until I already had the baby my last pregnancy.
