At what point do you decide to do growth hormone testing on a kid? My little seems to be following a curve - but it's so much more shallow than the curves on the growth charts and he has continually fallen farther below the 3rd percentile curve. He is only 29.25" and 18.5lbs at 21 months old and seems to be severely "off the charts", especially for height (I feel like his low weight is directly correlated to his short height - so weight is less worrisome - but it seems to be the only thing that everyone focuses on - perhaps because it's the only thing we can attempt to "control"). He's always been little.. Not sure where to turn, but I've always posted here and got good peace of mind.
His pediatrician seems okay with it, and I am okay with it for the most part. We've never been asked to do extra weigh-ins or extra testing. I'm not sure if it's something I should be suggesting? Occasionally I get very freaked out when I see 4 month olds that are bigger than he is at almost two years old! We very frequently get comments on how well he can walk/talk/etc. because people think he is a lot younger than he is (he's got a baby face and still very thin hair which doesn't help his cause).
Birth - 5lbs 15oz, 20"
3mo - 10lbs 5oz, 22.5"
6mo - 14lbs 6oz, 25"
9mo - 15lbs 11oz, 26.5"
12mo - 17lbs 0oz, 27.5"
18mo - 18lbs 1oz, 29"
21mo - 18lbs 8oz, 29.25"
Also, I am 5'2" and hubby is 5'9" - so we are not tall but we are not extremely short like our boy is.
Still nursing at least 4 times per 24 hours, sleeps through the night occasionally, but more often than not he wakes at least ones for nursies. He eats solids well and has regular BM and wet diapers. We are working on potty training when we are at home.
I like that his pediatrician is not pushy or labeling him as "failure to thrive" but I don't know if I should just go along with the passiveness that the doc has - or if I should be pushing for testing to rule out (I don't even know what). I don't feel like it could possibly be a food allergy or celiac's disease...but should I be concerned about a growth hormone deficiency at this point? I have done small amounts of research and at this point I would not be on board with giving him growth hormones - so is there a reason to have him tested? I think if I expressed concern his pediatrician would see it as valid and not argue.. I just want to make sure I am doing the right thing by not pushing it with my ped?
It's stressing me out today. Here's my sweet baby:
