The opposite of scheduled feedings, feeding on demand occurs when the baby "tells" you that she is hungry. Rooting, sucking on her hands (or attempting to), and crying are all cues that your baby is ready to feed. During growth spurts, parents are often confused by babies who were nicely scheduled and have gone the way of feeding on demand. This is normal and to be expected during these times.
It is recommended that breastfed babies feed every two to three hours during the day. If a baby wakes himself to feed within that time period, he has set his own schedule and he is essentially feeding on demand at the same time. If not, it may be necessary to awaken the baby and encourage him to nurse. If he is gaining weight, stooling and urinating frequently, and breastfeeding well during the day (at least 8 to 12 feedings), he can feed on demand during the nighttime.
