A Lesson In Statistics

Alright, we are going to go back to undergrad statistics here so follow me for those of you who can remember that far back.

So here is a bell curve, the bell curve is a visual representation of where you fall in relation to a large population.  So when you are a mother and your pediatrician says your son or daughter is in the 50th percentile that means that they are average, they are right in the middle of the bell curve.  So in a group of 10,000 6 month old infants your son or daughter weighs the same as half of them.  As you move either up or down in the percentages all that is is a % based on how your son or daughter measures up so to speak with the other 10,000 infants in that age group.  I’m using 10,000 as just a number here, I have no idea how many babies they use to determine the curve.  I do know however that it is large, huge in fact, so 10,000 is probably a small population in their world.  The larger the population you utilize the higher the chances are that everyone will fit on the curve. 
Then there are outliers, so when you were in high school and you had 4 tests a year and that was your entire grade  you wanted obviously to do relatively well on all of them because if you had just one outlier it would throw your entire grade off.  Say you get 90’s on 3 of the 4 tests, but the last test you bomb and only get a 20, your grade was going to be in the 90’s, now its in the 70’s because that outliers pulled your average down.  Just like when you were in high school, babies can be outliers too.  So those babies that are in the 99th percentile and the ones who are in the 5th percentile are outliers, they are pulling the average number either up and down.  Complicated I know but I want you to have a good understanding of what I’m talking about so when I say that my child is no longer on the scale.  I mean he has fallen below the 5th percentile and no longer ranks on the weight scale for his age.  He’s on the Definitely less than others portion of that visual at the top of the page.
Of course I’m concerned, as everyone tells me to not be concerned I’m his mother and its my job to be concerned where others aren’t.  He is doing fine otherwise, hitting all his milestones, height is fine, head circumference is fine, not huge but at least on the scale.  It’s just his weight, the kid does not eat.  I swear I don’t think he has been fussy for food since he was 5 months old, he could eat everything you give him (rarely if ever) or nothing (much more common) and he is always ok with it. It’s crazy really when you think about all the stuff his body is doing now, how active he is, that he barely eats.  I will say I think it might be how active he has become in the last two months, the kid never stops moving, ever.  Even when you are holding him he is constantly wiggling, dancing, pushing something just to get your attention.  If he ever did stop for 5 minutes I’d think he didn’t feel good.
The plan is go to for a weight check in three weeks and see how he is doing, if he still hasn’t put on any weight it will be off to the nutritionist we go.  Don’t ask me what a nutritionist does for a baby, its not like I need help understanding how many servings of vegetables versus candy to give him.  Hell at this point I would feed him ice cream for breakfast lunch and dinner if he would eat it.  But I suppose they have to work with the parents to figure out why the kid just doesn’t eat. 
So I’m taking suggestions, stories or other plans of action for those of you who have gone through this.  Let me say I have tried to give him literally everything under the sun, it does not appear to be a texture issue and yes I have tried adding butter whatever finger food I give him ;).
