baby hates everything lol

Hannah
Every time I change my baby's diaper he screams bloody murder and holds his breath between cries. So bad he will turn purple. I sit him up immediately when he does this but it drives me crazy and makes me hate to even try to change his diaper. He is also like this when I try to give him a bath (sponge bath) but it's even worse. I haven't bathed him in a week bc he hates it so much. He's 3 weeks old. Anyone else's baby like this? Anything I could try to make him more comfortable during these times
