Hi ladies!

I'm fairly certain DS has sleep apnoea.
He -
• Stops breathing occasionally in his sleep - not really frequently but much worse when hes sick.
• Sleeps with his mouth open
• Snores
• Grinds his teeth in his sleep - I can hear him grinding them from my bedroom.
• Recurring throat infections (Hes been on antibiotics for 3 in the last 9 months plus random temp spikes, colds and minor viral things he hasnt been to the gp for almost always accompanied by a sore thoat/blocked nose)
• Is constantly tired and short tempered during the day
• Hyperactive, difficulty concentrating, behavioural issues, changes in behaviour - he used to be such a placid little guy and is now getting steadily more difficult despite my best attempts to help him.

It sucks and Im scared but I also wonder if this diagnoses could solve our problems? Could the answer be as simple as this?

What is your experience?
How long until he can be seen in the public system?
How much is it to go private?
What does the diagnostic process?
If he is diagnosed, what can we expect?

Thank you.
