Milk problems....

Amie

Questions all the mommy’s out there :) I’ve been using aptamil comfort milk for my 7 week old and his very fussy and unsettled and I’ve had people tell me that aptamil isn’t the best milk and I should try him on something else but I’m not sure if to change his milk in case it makes him worse. Has anyone else had issue with aptamil? Help New mom!!!!!
