<grinning> My son was drinking apx 19-21 oz PER FEEDING when he was a week old. And that pretty much continued for as long as he nursed. Some months it increased, some it decreased, but it hovered at 20oz average. (We used the lactation consultants through the Hosp he was born at with their super-sensitive scale...and were part of a nursing study...which is how we know this eye-rolling detail.)
MY GAWD was formula expensive when I lost my milk @ 9mo, and he was already on partial solids by then.
My point is; babies eat until they're full, or the breast runs out. Your little one's probably either hitting a growth spurt or is trying to tell you she's still hungry, or has gas. If long burpings aren't working (try 20 minutes)...it's most likely one or both of the first 2.
It is the RARE, SUPER SUPER RARE, exception of a baby that needs to be put on a diet. In fact, studies show that infants, children, and adolescents who are NOT put on diets or restricted in their eating AT ALL (as long as it's healthy), are the ones who tend to have NO WEIGHT ISSUES WHATSOEVER throughout their lives.
Not that I'm saying you're not feeding your daughter more because you're afraid your baby will be fat, merely a cultural thing. I fall into it in my own mind with my son all the time & I've had to write papers on this, and sooooo many of the mom's i know IRL struggle with it, that I thought it might be pertinant to bring up. If it's not pertinant, no worries! Obviously my own bias. I've struggled through and let him graze, munch, pick, or gorge as he's felt like (umm...minus at halloween ;) and as a case study, he's about 6inches taller then normal for his age(Nordic, thats the genes), but he's actually a little underweight. When BOTH sides of his family struggle with being overweight.
Hmmmm....things to think about.
Good Luck!
