My daughter has always been small, she was born 6 lbs even and by her first pediatrician appointment she was down to 5#2oz. She's been exclusively breast fed her whole life, adding in solid food when she was 4 mo per her docs advice. She's now 18 mo and she only weighs 17#7oz and her height, weight and head circumference has all plateaued. We've seen a nutritionist through children's hospital who wants her to drink pediasure, take a daily multivitamin and breast feed less often. The problem is she doesn't like milk (I have never liked milk either) and pediasure tastes like flavored milk so she doesn't like it. I don't know what to do to get her to start gaining again. I'm worried because I was told as long as her head circumference didn't plateau she was still okay, but now it's stopped growing too. She's ahead of the curve in all her development other than growth though. She talks more than most 18 mos she's practicing jumping, she has no fear with climbing (she's been walking since she was 8 mo), she sings and dances all day long. She's just stopped growing...? Why would she just stop growing?
