Congratulations on a good first night

. I am so happy to hear that it went well. Chris only made it 3 hrs the first night, 5 the second and 10 ever since. He's off to a great start

.
To help him out, you might want to make a hose cover. Chris doesn't like the feel of cold plastic on her skin when she is sleeping. You can make one out of tube socks, polar flece or anything you have that you can wrap the hose with. Another suggestion is that when he finds the right place for the straps, that you mark the the proper settings with a marker so he can find them if the straps get undone.
He has the same machine and mask as Chris, but her setting is 4-10, but is usually less than 6.4. Chris loves her mask and machine. I hope your son will feel the same way soon.
