Another Baby's Eating a Lot Thread

So Breanna is 4 months 3 weeks and she's always been small.

As of last week, she was just under 13 lbs. (Born at 7 lbs 9 oz)

It seemed like she is always eating and eating a lot - and I figured out that it's now 36 to 48 oz a day.

Both my husband and I are bigger, and my 3 year old weighs 50 lbs. So I have this little baby who eats a ton and is always on the bottom end of the growth charts. She has a nice growth curve, but it still worries me that she can eat so much and only gain a little bit.

Any ideas?

The weight gain slows down after a while. As long as shes gaining some weight its fine x
