Am I wrong for being annoyed?

My boyfriend lets his 3 1/2 year old sleep in bed with us sometimes 😤 don’t get me wrong.. I don’t dislike kids— I too have a 3 1/2 year old that SLEEPS IN HIS OWN ROOM/BED

I am starting to get annoyed with it. His son will legit cry and scream until he gives in and we all three end up sleeping in bed together /: ugh lol

My son and I are moving in soon and our sons will be sharing a room with a bunk bed... I’m worried his son will still do this lmao.

Advice?

Should I be annoyed like I am?
