Factors that can affect milk supply include:

 Amount of sleep a mother receives  Mom's diet & nutrition  Her state of mind  Mother's age  Whether this is her first child or sixth  Mom's desire to breastfeed  Her capacity to nurse  A mother's nursing techniques  Her baby's ability to properly latch on

If you're nursing, keeping tabs on your baby's growth is incredibly important--your baby's life depends on it. How will you know if he's getting enough milk or nutrition? Unfortunately, the breast tissue isn't transparent and we cannot see exactly how much milk your baby is drinking or your body is producing. Fortunately, there are other ways to achieve our goal.

Within 24-48 hours, your baby should start having wet diapers, increasing to two or three per day.

As your baby works at sucking colostrum and then milk, you should hear a pattern of "suck, suck, suck, swallow." This will be rhythmic and there will be no "clicking" noises--clicking indicates that your baby is improperly latched and potentially isn't getting a good amount of milk from you. If you hear this, unlatch him from your breast and re-attach him. If it continues, talk to your pediatrician.

In the second and subsequent weeks of life, you should also notice 6-8 wet diapers a day in addition to at least 3 stools per day. His urine should be clear (not yellow), and he should be gaining alertness as each day passes. He should also be growing and gaining weight--weight gain is the surest sign of healthy growth. Any two days in a row of deviation from the growth indicators listed should be reported to your pediatrician immediately.
