My newborn is 10 days old. He sleeps for 3-4 hours during the day. Can I wake him up to feed him or should I let him sleep till he wakes up himself?

A. Hello, It is not necessary to wake most older newborns up to eat. However, those younger than 1 month old or so may not wake up when they feel hungry. Babies younger than 4 weeks old should not go longer than 4–5 hours without food. To wake a baby up to eat, try brushing the side of their cheek.
