My teen has been wearing a brand called Depends. It’s supposed to be a light and nonbulky diaper. I don’t understand, please help.
Not sure diaper is a good idea. It can hurt his self esteem, making him feel helpless.
Unless this is some known medical condition and doctor advised to use a diaper, I'd have him just sleep normally, and if he wakes up wet during the night, help him change sheets, and get back to sleep on clean sheets again.
This way he should feel both more comfortable, and more in control over his actions.
If you prefer a diaper anyway (e.g. what I said before, medical condition) then I'd suggest a different brand that can be more comfortable on the skin, and absorb the urine better. From quick look in amazon, for example, the best rated brand is this. Surely there are others, you can try few different brands and see which feels best for your teen son. Good luck!
