I have a 3 week old baby and i breast feed and do formula , he be fuzzy and getting red from his face and he didn't poop yesterday or today is it norm?

Infantile colic: Intermittent Fussiness , crying with red face at this age is highly suggestive of infantile colic. Try Simithicone drops or gripe water. 1-2 days without stools is also quite acceptable for most infants. Let your pediatrician chech him for 1 month check next wk and if he develops other symptoms.

Hard or pellet-like: stools are a sign of constipation. If an infant of 6wks. or younger strains to pass soft stool, it can be normal. The smooth muscle of the intestines is not yet coordinated to propel its contents, so they may draw up their legs, grunt, turn red in the face & use voluntary abdominal muscles to assist. Solely breast-fed babies hardly ever have hard stools; adding formula can make them harder.
