Sorry I know this is a dumb question, and I'm pretty sure you can't.
My DD2 is 17 days old and is a real milk monster. She was 8lbs 3oz at birth and on day 15 was 10lbs!! So she put on almost 2lbs in two weeks!! This means she's jumped from 75th centile at birth to 91st now.
Am just wanting some reassurance that I'm not overfeeding her? She feeds every 2 or 3 hours and tends to have a 10/15 minute "snack" followed by another 10/15 mins about 20 mins after that. I give her the same breast for both "snacks" - although given her weight gain I guess there isn't much worry that she's not getting hindmilk...!!
TBH, it is really ironic to be posting this as I had slow weight gain issues with DD1 and was told to top up with formula, referred to a paediatrician etc etc. So when I was pregnant with this baby I thought "that's the one thing I want to avoid" - and now I have and I'm still worried !!
