BF is about supply and demand. If you don't bf regularly and on demand when you're geting a milk supply going, guess what? You won't make enough milk. Your body is smart it will make as much as your child needs. Women can feed twins, even triplets on their own breasts. Trust your body, it cared for your baby for 9 months now let nature do it some more. Very few women are biologically incapable of lactating and making plenty of milk. Experts agree that only 2-5% actually do have problems making enough milk. Failure to thrive is different: but isn't necessarily a baby who needs to be fed with formula. First thing to do is bf more often. After that baby still isn't thriving formula is a good supplement. If the baby is failing to thrive figure out why. Seek help from a lactation consultant!

We have a real interest in measurable quantities in our culture. Don't do this!! The best way to make sure your baby gets enough to eat is to pick up on his cues. You may just have fed him, and he may still be signaling that he wants more. Your best guide is your baby. Put him on, let him drink to the point where he's sated, then let him initiate coming off.

Babies go through normal growth spurts. When this happens your baby will appear hungry and unsatisfied. These occur about: 10-14 days, 4-6 wks, 3 months, 6 months. Don't get discouraged. Baby may nurse twice as often for 24-36 hourse. This is the way your baby increases your milk supply to satisfy his/her growth spurt.
