DS is 19 months and has been having lots of nappy-free time as he’s got a rash from sweating in his nappy and the skin needs to air. Since he’s spending every afternoon naked and I’m mopping up wee anyway, I wondered about introducing a potty. I wasn’t planning on proper potty training as he seems a bit young, but I don’t want to confuse him/cause problems later by not doing it fully. Is it too soon? Any advice on how to encourage him? He loves books so I thought one about using a potty might help - suggestions welcome.
