Hi, I'm at my wits end. My child was born full term at 890g and 29cm. The Dr's put it down as "unexplained" and said i should thank my lucky stars he's healthy. We eventually got him home after 3 months in ICU. He's a happy, energetic child and i wouldn't change him for the world, however at 5 years old he weighs only 11kg's! He has NO appetite, and that's been since he was born. He can go without food for a days unless i force feed him, and he keeps asking "why" he has to eat??? He survives on one slice of cheese a day! We've now put him on HGH injections but that has done nothing to increase his appetite (he measures 92cm). So while he's grown 1 cm in 5 weeks (which i am grateful for) he still asks why he has to eat. He is just not feeling hunger. I am starting to wonder whether something else could be wrong besides the usual Dr response of his case being unexplained! He appears healthy every other way, just is painfully skinny!
