My son, nearly 3, has been hospitalised 3 times. Every time he was breathless, the last time was far worse & he needed to be on oxygen overnight and when he slept. He was only in 2 nights though. It is hard to gauge whether or not 3 times in a year is a lot or normal? He has barely attended nursery. No nursery at all during lockdown and since September he's been a total of about 6 mornings as he's been ill twice & it takes him a while to get better. I have pushed for a brown inhaler as at the moment we don't feel relaxed at all. He goes downhill very quickly when he does become breathless. All 3 occasions have involved him fighting a virus. Is there any reason why not to try the brown inhaler on a low dose?
