Our pediatrician said to take the # of weeks old that the baby is & give her that many ounces. There is obviously a cut off point to that but so far it's been pretty accurate. This past week the baby has been taking between 2-3.5 ounces every 2-3 hours, with the exception of a cluster feeding Wed/Thurs when she was drinking 1-2oz every hour to hour & a half. I pump, BF at night & supplement with formula for 2-3 feedings a day.
Re: how many oz./feeding is your 12day-14day old getting???
This, although my son is only 10 days old.
