Welcome to the Cpap world. I’ve have mine for about 10 years, yes it’s scary at first and the first few nights can be difficult. But trust me it’s worth it. It’s changed my life.
so at first it can make you feel claustrophobic I’ve found having a fan gently blowing on my face stops this. You will also get a very dry mouth, so have a bottle of water to sip as needed or speak to them about have a nebuliser (I personally prefer to sip water.)
I wash the mask every day, just in hot soapy water it takes seconds to unclip and wash when you clean your teeth. The tube I do once or twice a week again in the sink and I leave it dripping over the shower rail. The filter you need to clean every week too, they will show you how.
my mine issue with it is you need it tight enough to not leak, but this gives you marks on your face. Some people wrap things round it ( just google or look on TikTok). I find this uncomfortable and even more claustrophobic the marks are gone by the time you showered and dressed anyway.
i honesty can’t sleep without it, and you really will feel the benefit so quickly.
edit to say, don’t worry about the children, mind thing it’s great and love to get hold of it you will have trouble stopping them, the novelty wears off thank goodness. But honestly just make light of it ( it’s known as my crap machine 🙄). They will soon just see it as the norm.
