Here's how my 8 year old son is breathing: inhale, long pause (4+ seconds) then exhale with a somewhat squeaky sound sometimes (not wheezy, but like he's, well, squeaking)...
What is causing that? Why is he doing it? Is it his asthma? It happens when he's asleep sometimes but also can be when he's awake. He's had his adenoids and tonsils out (due to sleep apnoea) which made a huge difference. Is it a breathing tick?
