Hi. Im a first time mother to my 1 month old. I have been breastfeeding but have to supplement as he doesn’t get full from me. Lately I have started pumping and when I pump I get about 130ml , which when I give him it in the bottle it always fills him up. So why does he not get full when I breastfeed but I know I have enough milk to be filling him up?
