I started to potty train my wee boy about 8mths ago, he is 2.8 now. I kept one potty in the loo and one in his bedroom on a plastic mat ( just in case )
As soon as we had started potty training, we didnt use any nappies at all, my wee boy didnt too well with getting the training pants down in time
So he was always in pants, and we just took a change of clothes everywhere with us.
Getting to know when he is likely to need to go, after drinking or eaing lots etc. Helps know for timing, so you can keep asking him if he needs to go.
We found it good to ask his nursery/nanny person to continue this when he went ith them, because ordinarily they would put him in a nappy and he would need 'retrained' when he came home.
I dont know if this helps, but good luck.
Oh, and make sureyou get a waterproof matress protector thing, as have just had to throw out a mattress after forgetingto put it back on the bed after it was cleaned.
