This is one of the fascinating mysteries of life. After many feedings and being up at night, some parents will be tempted to daydream during feeding time. These parents miss the wondrous feeling of communicating with their infant and the opportunity to let their baby learn from them. Talk to your baby. The sensory stimulation will enhance the baby's development.
Some babies feed often during the day and sleep all night.
Most infants, however, will get up once or twice at night for feedings. Given that this style is not much fun for the parents, if your baby displays this pattern, you may want to encourage your baby to try to eat no less than every four hours during the day. Hopefully the baby will be satisfied with your efforts and will sleep more at night. In the case of this reverse pattern, even without intervention, babies will often begin to sleep more at night and eat more often during the day at about two weeks of age, with completion of the change usually by one to three months of age. Fill the bottle with about one-half ounce more than the baby usually takes.
