My son Noah is 8yo, was dx'd in March of 2005 and has Athsma and allergies to peanuts, pennisillian family, and sulfa. Noah was in the hospital with DKA in 2007 the weekend before and the weekend ater Thanksiving that year. He lost about 5lb. His weight was checked about a month later and he only gained about 2lb back. However, since then he has been relatively healthy with only small bouts of DKA and he has still yet to grow in highth or in weight and it has been over a year.
I had done some trouble shooting and desided to wein him off his daily flovent and flonase treatments for his Athsma because his athsma has been doing very well. That was about three months ago and he still has not gained weight.
I should probably mention that Noah has no problem eating. He will eat 3 meals and 4+ snacks a day. He had been drinking soy milk and now I have put him back drinking organic cow milk. It has been about three weeks at that. He looks like he might be gaining a smidge but, that is when I am squinting and the sun is in my eyes. ;-p
