I have a 4 month old whose weight gain has been the following:
Birth weight: 8 lbs 8 oz
Low point (as far as we know): 8 lbs 1 oz
1 month: 10 lbs 13 oz
2 months: 12 lbs 1 oz
4 months: 14 lbs 1 oz
His doctor was never concerned about his weight gain until his last appointment, at 4 months. At that point he evidently dipped into a lower percentile, and his doctor said we needed to be helping him gain more.
To be honest, I don't have a lot of confidence in his doctor. He is a family doctor (not a pediatrician), but more importantly he has said several things in the past that I have questioned, and on breastfeeding issues in particular he doesn't seem to be stellar. We'd like to switch but we're probably moving in a few months so we've been trying to just hold out until then. So, I want to take what he says seriously but I don't know how concerned I really should be about his weight gain.
He wets frequently and poos about every other day, he's growing wonderfully in head circumference and height (he's 97 percentile in height), and he's very alert and happy when awake. If you had to guess simply by looking at him you would definitely get the impression that he is thriving.
So I have two questions:
1) How concerning do you think his weight gain is?
2) How can I encourage him to eat more?
He has always nursed very fast, usually only 5-8 minutes, usually on one side per feeding. I know fast can be fine if he's keeping up with a fast flow but I don't know if he's doing that or simply stopping before he's fully finished for some reason.
The most obvious strategy would seem to be to offer more frequently, but there was a time when I was offering too often and he would get upset and pull away even more, so I want to be careful about not pressuring him too much again.
Thanks very much for your help!
