Hi, my 3yr old son very seldom breathes through his nose, he is a very noisy sleeper/breather and often when sleeping he stops breathing and after a few seconds gasps loudly in between snores. His breathing sounds more like a rattle than a wheeze and we have had inhalers from our GP as he thinks it asthma related although there seems to be very little improvement. Other symtoms include drooling, choking occasionally when eating and his speech is sometimes hard to understand. Could it be adenoid related?
