I did a 3-day intensive potty training weekend with both my girls
We would set a timer for every 25-30mins, and when it would go off it would be "potty time!!!" make a huge deal, make a potty song etc, and they sit on there. If something actually comes out you have a party and give them a reward. For us it was a sticker chart. Poos got two big stickers, Wees got one. Sitting on the potty got one little sticker.
Both my girls got the hang of it really quickly - I just found that you have to be really consistent - and have the potty handy, like in the lounge.
All the best! Its hard work, but I rekon if youre going to do it, you just have to DO IT!
