Newborns should be fed every 2-3 hrs(day) to establish a good milk supply. It is important not to let them sleep all day so they eat enough and will sleep better at night.
Breastfeeding is a really personal relationship, each baby/mom pair is different in how well the baby latches on, how much milk mom has, etc. Some moms feed every 1.5, some moms feed every 3-4 hrs (day) It just depends on what works best for you.
