Are all babies expected to double their birth weight by 4 months? I read that somewhere recently and didn't know if that applied to both breastfed and formula fed babies.
My son was born at 8lbs, by two months he was 13lb 4 oz, but then weight gain slowed and he was only 14lb 11oz at four month checkup. My ped wasn't concerned because he had jumped way up in height, but I still worry a bit. (I had supplemented with formula some in the beginning, but had stopped that by 3 months.)
It doesn't help that there are so many women around me that had babies at the same time and they keep asking me how much he weighs, then telling me about their huge 18-20lb babies that are off the charts. Why does everything have to be a competition!!??
