Thanks everyone I think I will just buy a cheap potty and give it a try first and see how she goes. I'll just pop it somewhere and see if she's curious. We have floorboards so that will help with accidents lol. If she's not keen on the potty I'll try the big seat. Aldi has them for $15 next week I do like the idea of a potty in the bathroom. I'm thinking the sound of the bath filling up could encourage a wee??
