I'm a FTM to twins, a boy and a girl. They're 9 days old and my boy has an allergy to the protein in cows milk and he was constipated but ended up pooping yesterday 3 times in a row but he's still very fussy and won't sleep for longer than an hour at a time or won't sleep unless he's being rocked or feels some kind of movement. He switched his formula from gerber gentle to enfamil nutramigen and he's been on it for 2 days now but he hates the taste of it so I have to feed him with a syringe in order for him to eat it. Is he too young to be colicky or do you think it's just the switch of his formula from gerber gentle to enfamil nutramigen that's making him not be able to calm down and relax? Just looking for advice from anyone that has dealt with the same issue. It breaks my heart not being able to help him relax for very long.
