I've been struggling with poor weight gain in my now 11 week old baby.
Reading about the growth charts I see lots of comments that if the weight is more than 2 centiles higher then the length then baby is over weight and BMI should be looked at etc. But they don't say anything about what should be done if the weight is more than 2 centiles lower than the length.
DS is near the TOP centile range on length for his age but his weight is near the bottom of the centile range.
In the weight for length chart he isn't even in the curve anymore.
I'm worried about being diagnosed with failure to thrive but he seems so happy and alert and is meeting developmental milestones on target and some milestones ahead of time (like being able to lift head to 90 degrees while holding chest up with arms and rolling over one way from tummy to back.)
Should I worry and if so what should I watch for most or should I not worry about it and just be happy I have such a lean happy baby.
