Yes that would be a challenge if a toddler kept trying to take it off.
Also probably not a sexy look for a young person, but I am old so it doesn't bother me
I tried many masks until I found the one that works for me so it takes a bit of perseverance but you do get used to it eventually.
I found that nasal pillows that sit just under your nose with a light headgear worked best for me.
The other thing is their is a machine called an APAP that adjusts the air pressure automatically depending on what your breathing needs, but they can be more expensive than the set pressure CPAP machines though.
In Australia a lot of the sleep clinics will let you hire a machine and mask for a while to get the best combination that works for you but not sure about India.
It was truly life changing for me and I have been using it for many years now and can't sleep without it.
Good luck with it.
