My husband and I are arguing

And we rarely argue but it seems like for the last 6 months we argue at least 4 times a week. I've tried relfelcting and trying to change my approach to things so I could figure out where the problem lies but idk. I feel really distant from him. We have a 2 year old and both work fulltime. We are constantly busy but I feel like him and I are really growing apart. It sucks :( idk anymore... Needed to get it off my chest.
