Planning to start potty training this weekend. I've got four days in a row we can focus on it. DS is 29 months. I've read Oh Crap book, I know it says in there pants off is best method but by the third or fourth day I'd like to get out and about with DS. Are there any really good toddler training pants that don't feel loads like a nappy but will contain a small accident rather than putting him in just trousers and no underwear?
