My little boy is 18 months old, recently I think he started to show signs that soon he will be ready to be potty trained. He hates having a wet nappy and will pull it off as soon as he's gone for a wee/pee or bring me a new nappy to get him changed. He cannot yet say wee or poo so I don't know if he has the understanding to be potty trained just yet. But I'm not really sure how I potty train. Do I just let him run lose with no nappy? How do I do it when I go out? At bedtime does he still wear nappies? What has worked for everyone please help
