Hello, my baby is 3 months old, at night she sleeps for longer duration , that is more than 8 hours in a stretch without feeding, for a one time feed, i pick her up in her sleep and feed but by that time she is wide awake and she falls asleep back after an hour. should I leave her to sleep without single feed at night and wait for her to wake up? here when I pick her for feed her sleep is disturbed. please suggest.
