Question: my 11 week old is very fussy?
Answer: A common cause of fussy, colic-like symptoms in babies is foremilk-hindmilk imbalance (also called oversupply syndrome, too much milk, etc.) ... Babies normally fuss for many reasons: overtiredness, overstimulation, loneliness, discomfort, etc. Babies are often very fussy when they are going through growth spurts.
