Im thinking about potty training. ds is 23 months, maybe a bit young. Did all those toddlers out there already trained or training at the moment know how to pull their trousers down before they started or is it something that they learn how to do at the same time. Sorry if this sounds like a stupid question but it seems like quite a bit thing to me. ds can pull his socks off, take his coat off - but that's about it. he does lift up his t shirt but I think that's more to show me his lovely tummy!! any advice welcomed.
