My 20 month old son is very small for his age and my doctor has written to his paediatrician to ask him to do tests at his next asthma review in March to find out the cause. He is off the scale for his weight and height (weighs 19lbs and has gained less than 3lbs since he was 6 months old) and can't walk yet either, although he takes a couple of steps here and there (it's a real struggle for him though). He was diagnosed when he was 10 months old after repeated bronchiolitis and chest infections - and not eating for 4 months. He is on the brown inhaler twice a day and has 5 puffs of the blue inhalor 4 times a day whenever he gets a chest infection or cold - which is frequently. He's been on steroids twice. After reading some of the posts in this forum I realise his asthma is nowhere near as bad as other children. Is it normal for him to be so small, is this caused by his asthma? Also, he doesn't wee much! He drinks all day but I don't need to change his nappy. When I change it before bed, its so light but smells really strong. Is this related to his asthma?
