At that age...even breastfed babies can get gas and be uncomfortable...a little moreso for breastfed babies :(. It may end up working itself out in the next food days...hopefully! Poor kiddo! My mom swears by diluted chamomile tea...if he was older I'd suggest diluted prune juice...but 3 weeks old is so young...you might want to ask his pediatrician for some suggestions if it doesn't clear up!
