My just turned 4 year old hasn't gained any weight for 7 months. He was born on 75th, hovered around 50th, steadied at 25th but has now fallen into the 9th bracket (16 to be precise on WHO calc). I raised concerns 6 months ago as he was pale, very tired and I was worried about iron. He had bloods for anemia and coeliac but both came back normal. He had started a steroid inhaler for suspected asthma at the time, which helped energy a bit but now he is back at square one. He really struggles to make it through the day without falling asleep by 4pm, and if he doesn't sleep, he is an absolute mess and either inconsolable or complete menace. I will take him back to GP but interested to see if anyone had a child with similar symptoms? Most of the day he is a happy child, he has no gastro symptoms. He sleeps well, snores with cold but no apnea or anything. He starts school in September and he can barely cope now with 3 days at preschool let alone 5 days at school so im worried about that.
