My newborn is sleeping all the time not even waking up for feeding when i try to feed him he uses my breast as a pacifier for a few minutes and sleeps?

Mgt: Babies establish their own feeding patterns, and as long as your infant's growth and development is normal, their feeding pattern can be on demand.

Have baby checked: Has he been gaining weight as expected? If so, he probably is just a "happy" baby. If not, excessive sleepiness could be a sign of some serious illness, e.g., metabolic disease.
