I had been giving my son about 6oz of pumped milk for awhile. However, I had posted a message on one of the other boards on here that had lactation consultants and they said I should only be giving him only around 4.5 to 5 oz at the most. They gave me the calculator from the kellymom website and he feeds approx 5-6 times a day. It says if he feeds 5 times he should be getting about 5oz and 6 times he would be getting around 4.16oz. He doesn't always feed the same amount every day. So I guess now I know why I couldn't keep up with supply as I was feeding him too much. I give him a bottle before bed and overnight or otherwise he falls asleep and he wakes up hungry an hour later. I tried it Friday night and he did it again so I am stuck with bottles for overnight. Not sure why he does it but he does.
I also was told to use the slowest flow nipple and maybe that is why I was feeding him too much and he was taking it all. I feel bad I was overfeeding him but my doctor said that 6oz was fine and I never questioned it until I was not able to keep up with supply for bottles and had to supplement in formula.
I did 5oz before bed and he took it all and didn't ask for more. I'm going to try a little less today and see what happens. If not then we will stick with 5oz. She also said that they should be eating about 25oz in a day. I didn't know if this was correct or not but I was just wondering if any of you had ever had any issues or advice about this.
