Has anyone experienced this? My 5.5 year old is mildly asthmatic and on a steroid preventer inhaler. He has had this for around 18 months to 2 years and it has helped as before he often used to cough until he was sick. Recently though we've noticed he doesn't seem to be growing, he has dinky little feet and been wearing pretty much same shoe size for well over a year. His 3 year old brother has overtaken him on weight, size of feet and is rapidly catching his height. Could it be down to the steroids and should I be worried? Are GPs or HVs concerned about it at all and would it affect his height as an adult?
