We're not going to use either here I think. I tried seeing how Natty would go in a pair of undies a few weeks ago and over the course of the weekend she didn't do a single wee in the toilet. I guess she's just not ready. I sit her on the toilet before her bath each night and also if we are at home I sit her there each time we change her nappy. Sometimes she asks to go to the toilet too, but she still hasn't done anything in there. *Sigh* The waiting is hard. But I have heard it is so much easier if you just wait until they decide.
I also understand the pressure too - most of the other kids in DD's playgroup are toilet trained already, some of them younger than DD. But I'm trying to let Natty lead me in this one.
Good luck to you!
