FTT - No reason found?!

My 18mo old weighs  in at 16lbs and is just under 26inches.  She has plataued on the charts from 6-9 months on. She has "mushy" stools an avg. of 3-4xs a day. I have had a RAST test done (with no allergies), Celiac panel (negative), thyroid check (all good), Liver function (good), Stool samples for fat, parasites, etc. (all clear), CF sweat check and xray - clear.  I am greatful that all is coming out clear...but I am convinced something is not functioning properly.  On the advice of a nutricianist, I have pumped up her calories by adding to her diet. She is on a vitamin supplement as well as pro-biotics per the Ped GI.

I was told to wait a month to see what happens - we are three weeks into the diet change with no gains/changes in anything included BMs.  I would like to know what I should be asking the Ped GI next?  What is the next course of action?  There are 4 Ped GIs in our area, all work together.  I like the Doc. but I've gone as high up as I can; I think.

I must add that I am only 4'11.  I have no aversion to my child being petite.  I am concerned about her developement.  I am tired of people saying, I'm small so she is small.  I don't think this is a problem - or The problem.  I have a 3 year old who is on "target".  

Would love some advice and guidance.  Please!!!

I don't know what it is but just letting you know that a child can still have Celiac disease with totally negative blood panels.  You might want to try her on a completely gluten free diet for at least a month and see if anything improves.  The only 100% accurate test for Celiac disease is a colonoscopy which I assume is very difficult for a 18 month old.  You might want to get some more blood tests done like a CBC and testing her vitamins and minerals to make sure she is not malnourished from a disease or something.  Best of luck.

Thank you for your reply.  She had a Celiac Panel done with neg results..the Ped GI said with certanty "she does not have Celiac...she might develope it sometime but she doesn't have it."  When I asked about a Gluten free diet his response was "you can try it but why put yourself thru the stress.  She doesn't have Celiac."  Where should I go when the only one of 4 Ped. GIs tells me this?  

So, you reckon it takes about 1mo to see if the Gluten Free diet works?  Thank you so much.  I'm at my wits end.

Your doctor is somewhat right.  The chance is of having celiac disease and having a negative blood test is about 1%.  There is no definite answer for the amount of time to try a gluten free diet.  If you do it strictly for a month (that means 0 gluten) she should show some improvement in a month.  If that doesn't help or if you don't want to try that you should take her to a hospital known to have a good GI department.
