I've noticed quite a lot of British members here - myself included - seem to say "diaper"; however, in British English, the word is practically unheard of. To me, the word nappy has always seemed really weird - just reading it makes me feel strange and awkward. It seems to carry some odd feelings with it.
If I ever had occasion to talk about them IRL I'd call them "nappies", because using an American word would seem out of place. And if I was ever doing some TB roleplay, I would most likely say nappy, because it just sort of feels cuter - which I guess is one of the reasons I'd rather not say it at any other time. It's a lot easier to just say "diaper" online, because it just feels like a normal word. If I said nappy a lot I could probably get used to it, and I do really like the word - it feels kinda nice to say. But it's a lot simple to stick with diaper.
Anyway, I was wondering if anyone else felt a similar way about this, or if you just use the word diaper because that's just what everyone else says. And Americans: do you have weird feelings about the word diaper like what I described? And what do you think of the word nappy?
