My little guy is 20 months old and has two potty’s. When he sees them he always say peepee and sits on them knowing that’s what they’re for. Recently he’s been peeing or pooing in his diaper taking them off and giving them to me saying poo. My only struggle is he fights sitting on the potty. If I sit him there he sits for probably 10 seconds then gets up and won’t get back on until he wants to. I’m at a loss. He knows what the potty is for and when he has a dirty diaper, but won’t use the potty himself 😫
