Ok, am a whisker away from giving up and admitting defeat for now. Every success makes me think she does know what we're trying to achieve, but is outnumbered about 5-1 by messes on the floor. Every time I ask if she wants a wee / poo the answer is no, whether she does or not. The successes are generally when I've sat her on the potty and got her to stay there for a while.
We did have one day where at least four times, she voluntarily sat herself on the potty and wee'd. But just now I said her name five or six times before she decided to throw a glance my way, so I said "don't forget, on the potty if you want to do a wee" - no response, and then five seconds later she's peeing on the floor, and not just a little bit.
I'm 33 weeks pg, getting down on the floor to mop up piss every ten minutes is not funny. I have mentioned to Dh that it would be helpful if he could keep an eye on her too, rather than being completely oblivious and gawping at the TV. It's always me diving for the potty, and then cleaning up the resulting puddles.
Sorry, this has turned into a bit of a rant, it's just her completely blanking me is really starting to wind me up. She DOES know what we are doing, she has figured out the connection between potty and chocolate, and she has figured out that asking for the potty is a good way to get my attention if I dare to try and do anything else, so I don't for one minute believe she doesn't understand. Ideas anyone?
