We are staying with my SIL this Xmas (24 to the 27th).
My 12 yo ds still wets the bed most nights but has stopped wearing pull ups because he is embarrassed by them. I perfectly understand so just use a mattress protector and tolerate wet bedding.
However I think it's unfair on my SIL and her husband if he doesn't wear a pull up. I also think it would be more embarrassing for him to wet someone else's bed.
I'm worried that just by asking him he will get upset.
