It doesn't smell strongly, but there is a slight smell to it. I would definitely purchase a Pros-Aide sample and let him smell it and see if he has a reaction to it before you attempt to apply it. You may want to try several body adhesives too since as mentioned above, you can mix PAX using other adhesives besides PA, and some smell less than others.
You can certainly sleep in PAX. I don't super recommend it if you're doing complete body coverage, but for just upper body, that's probably easier than reapplying it every day XDD I'd put down an old sheet or something in case some spots on his back do rub off a little while sleeping.
