Hi fairy15
Now, I'm a Granny, so I don't claim to be a modern expert, but babies don't recognise new or old theories! I can only tell you what has worked best with my 3 kids and 3 of my 7 grandchildren.
Decide on the day you're going to start, and make sure you don't have too much on socially that week. Tell LO that now he's a big boy he'll be out of nappies and in big boys' pants (have a supply of easy-wash thin ones). Pop them on him first thing and put him on the potty or toilet every half hour, with suggestions of having a wee.
He'll wet sometimes, but without a nappy, he'll soon get the message of cause and effect. Calmly change and dry him, put on dry pants and reinforce that this was a little accident but he'll get the idea soon. Don't worry how many times this happens.
As the week goes on, he'll get used to the regular feel of the potty on his botty and a reflex will happen...he'll wee when you put him on!
Most kids of 2 and over will respond well to this, and my grand-daughter was able to go out in my car for short distances within the first week without wetting.
Wearing a nappy or any absorbent pants will weaken the message that " If I wee I'll get wet". Bowel training is another story,but your lo seems ready, so Good Luck!
