My daughter will be 4 months old in a few days and the pediatrician is concerned that she is not gaining enough weight. Each visit he asks me if my milk is "enough", and suggests I provide formula "if she still seems hungry". The problem is I have always had adequate supply and she never seems hungry after a feed.
She was 3030 grams at birth, but dropped to about 2665 after a few days. I was quite heavily medicated during the labour though so perhaps her birth weight was inflated. Since then her weights have been as follows:
1 week - 2.9 kg
7 weeks - 4.4 kg
9 weeks - 4.65 kg
3 months - 5.05 kg
4 months - 5.2 kg
Please note though, from 7 weeks on the doctor has weighed her with a diaper. The 4 month weight is on a different scale (I rented one so I could monitor), it also includes a diaper but immediately after a change.
I would like to try some pre- and post-feed weighings on my own to see if she is getting adequate milk supply. Any advice on what would be a reasonable gain?
Any help would be appreciated.
