another tt question

So, I've decided that I'd give tt a go with DD - now, she's only 19months, so possibly still a bit young, but it would be great to have her out of nappies by the time the next one is born in march. we use cloth nappies 99% of the time, so not sure if this will make a difference.

Anyway, this is what I've decided to try - any opinions, other ideas greatly received!
When we're at home, I've been putting her in cotton 'big girl' knickers, and then try her on the potty every 30mins or so. I've also got a good picture book about potty training that she likes reading.
We've been doing this since monday, and absolutely no luck so far - and there's a couple of issues -
firstly, she is happy to sit on the potty with a nappy or her knickers on for quite a while, but will only sit there for about 10secs with no pants on, or last night, she would sit with both her feet IN the potty and then crouch down - that was the only way she would sit with no pants on.
secondly, she doesn't seem to mind if she wets herself - doesn't complain if the knickers are wet at all.
thirdly, last night I was at work, and DH tried her on the potty, she got up walked to the kitchen, weed on the floor and had a whinge.

so, is she not ready for it? Should I maybe leave it and come back to it in a month? Any one else had success at tt this young?
I had a look at different potties in target - the potty we have was only a cheapie and has quite a small sitting area - maybe its not comfy on her tush? target had a couple that had a bigger rim, so this might be more comfortable? or I could go to one of the seats that fit in the normal toilet?

as I said, any help or idea would be great! TIA :D

When I tt Nina, I waited until she was showing signs of being ready. These were things like letting me know when she needed to do a poo, being aware of when she wees etc. She was 2 when I started, and it took 4 weeks.
19 months is young to start tt, however some do. Emily has started taking her nappy off and doing poos in the toilet (and wanting to do them in the toilet) but she'll happily do a wee on the floor :doh:
If it were me, I would wait until she starts showing signs. There's no point hurrying it, it'll only backfired and take twice as long.
As for the size of the potty, why don't you just use the toilet? Get a seat with a step for the toilet. That's where you eventually want them to learn to use the toilet anyway.

I don't have much advice, I started tt DS a couple of weeks ago, just after his second birthday and haven't had a great deal of luck. Well I have, he does a wee every time I take him to the toilet, but also wets himself in between toilet trips (i take him every 15 minutes!) and it doesn't phase him in the slightest. So, whilst he understands that you go to the toilet to do wees, he's not at the stage where he can tell me when he needs to go. So I'm not pushing the issue too much.

I do agree with Jodi and have done the same re the toilet seat. I don't like potties too much, as you teach them to go in there, and then you have to teach them to use the toilet instead of the potty. I just think they're pointless. A toilet seat and step is definitely the way to go for me :)
