Sounds like Alex is ready, Caroline. Why not start proper training on a Thursday then you'll have until the following Tuesday if you're worried about nursery? But they should be used to dealing with potty training anyway. A(n awful!) woman who goes to the same playgroup as us only her trained her soon at the CM until he got the hang of it. She demanded the CM had him ready in a nappy at home time! How lazy/rude is that?! My friend uses the same CM & the CM commented on it to her! I'd just put Alex in pants & not in a nappy unless he's sleeping.
