Is something wrong

I think my baby feeds too much , when he wakes up he feeds for the whole time he's awake whether it's two hours or one hour he sleeps only a hour and half and waje again ready to feed and all he does is cry if he's not feeding he's never laying down silent or just focusing he is just constantly crying and feeding and about three days again his lips started turning purplish grey they are stil that colour and it's starting to worry me
