Your milk may take up to a week to come in. That's NOT a problem! I promise, you are making more than enough! Look at baby's eyeball... YEP! That's the size of your baby's stomach that first week! : ) It gets filled quickly and empties quickly, so LO will be hungry a lot, but that builds your supply. Also, you cannot tell if baby is full by how fussy they are. Remember, LO was swimming around in a nice warm place for nearly (or over) forty weeks and is just adjusting to being a land dweller- so expect him or her to always be squirming and fussing, it has nothing to do with your supply, they are just trying to adjust! How much you pump is NOT an accurate indication of supply. Your body was designed to respond to a baby, not a pump. : ) Average production for a pump for BOTH sides is anywhere from HALF an ounce to two and half ounces! All that said, how DO you tell if you are making enough for baby?! What goes in, must come out, right? ; ) So, we go by diaper count! Expect the diaper count to match the day (two diapers on day two, four on day four) the first week. Then, after one week, you are looking for 6-8 diapers a day (poop counts as two!). I hope this helps!
