My baby is now 4 months old and still wakes 3 to 4 times at night. How much sleep does my baby need at this age?

Based on guideline, they should be sleeping about 10-12 hours in total. Not all babies will be able to sleep thru the night. At 4 months old, most likely they get up because of hunger. My lo who is 3yo still will get up one time. During the younger days, three to four times seems like a routine. End up I always looks like a zombie in the morning. Lol
