So a weird kind of question, but I need answers lol

I’m curious to know if you put your kid to bed in underwear. Like obviously pjs, but do you put underwear on them?

If not, can you please let me know why?

And is it the same for boys and girls?

This question is coming from when my nieces and nephew come over, they don’t put underwear on at night time.

I figured the girls didn’t because it’s good to let your hoohaa “air out” but what about the boys?

I’ve noticed a couple of my parent friends do the same, their kids don’t sleep in underwear.
