Another TT question...

I have done a search (and read through lots of paes in the main thread) but can't find anything about what I need. DS is still young but has shown an interest in the potty since we got it and will even take himself to it for wees (not consistently - sometimes he will bring me a nappy, or several until I put one on him). He understands what it is for and his latest thing is to sit there, and let go just a little bit, jump up 'Yay!' high five etc.. big clap, get me to take it to the toilet (or try to take it himself), tip it in, wash it out and then he does it again and again He must have fairly good bladder control, and I think he just likes the praise after he's been, but I'm thinking stopping and starting like that can't be very good for him??? Any suggestions please???

Tess is showing an interest as well, she started bring the potty out and pulling at her nappies so after meals I ask if she wants to, she goes and gets the potty and 'reads' while sitting. Last week she did number 1 and 2, we made a big deal and will continue to do that, I am fully expecting her to lose interest but we will just go with the flow, I am not going to get stressed about it with number three not far away!
