In the early days and weeks, your baby may need to eat every 1-2 hours, or more. Twelve feedings in 24 hours is not uncommon.
Feeding your baby on cue early helps to bring in a full milk supply and maintain it.
Another reason for low milk supply is that the baby is not latched well to your breast and is not removing all the milk he or she could be getting.
If you think your baby might not be getting enough milk please seek help from your healthcare provider or a lactation consultant.
