if baby is sleeping for 4-5 hrs at night is it ok or we need to wake them and feed

A. Most pediatricians recommend that you wake up your baby if they are due for a daytime or nighttime feed. Babies shouldn't go without feeding for more than 4 hours. So while most of the time your baby will let you know when they are ready to eat, it's okay to wake them up if they snooze past the 4-hour mark.
