If your baby is voiding pale straw-colored urine 6 to 10 times a day, your milk is sufficient.

Weigh the baby before and after each feeding to see if she has gained any weight as a result of the feeding.

Offer the baby an extra bottle of milk after her feeding, and see if she is still hungry enough to take it.

If you're concerned, bottle feed your baby so that you can see how much milk your daughter is taking.
