my son is 2.5 months old . he sleeping 12 hr a day only. is it normal. also he is sleeping continuously 6hr then wakes up for milk again he is sleeping . is it ok for the baby . please answer me

If he is sleeping long hours in the night then it's actually great as he is setting his sleep routines and adapting to life outside the womb. 12 hours is fine as long as baby is gaining well and is happy. Additionally keep track of his urine. An exclusively breast fed baby will pass urine seven times a day as a minimum.

is 12 hour sleep happening at day time or night time
