Struggling 😔

Jessie

My LO is just 3 weeks old. He has cried non stop today. I am breast feeding and all he wants is to be on my boob constantly. I’ll nurse him for a half hour and a half hour later he is screaming and rooting... idk what to do. Yes I’m producing enough he had a dr appt yesterday and gained 1.4lbs in 12 dats
