suddenly unsure

Hi all :)
DD started TT a few months ago, I didnt think she was older enough but my mum who we live with atm was all "you kids were all toilet trained by 18months, bla bla" so she would put her on the toilet in the mornings & she would do a poo in there, and would be quite keen on going in there, she would put her little seat on etc. She seemed to be really comfortable with it all. She liked to wear knickers but would have little accidents. but she was very confident on going in there. I didnt push it really, Im in no hurry for her to be TT. It wasnt a full time time thing, maby if i did be really onto it she would have go it. But then she was pretty sick afew weeks ago, very bad diorreah (sp?), stomach cramps, 2 hospital visits and after a course of antibiotics bad nappy rash. It was a horrible week and I went thru a whole box of nappys in one weekend to put it into perspective! Now every time she gets a bit of a tummy rumble or passes wind she starts saying "poo poo" and gets quite worried :( like shes scared its going to hurt. Shes getting a little better now not as worried. She tells me when she needs to do poo's but when i say lets go sit on the toilet then she says no and walks away. I dont want to force her in there, I did one time and she was okay as soon as she sat on the seat, we sang some songs etc and she was telling me "poo" so she needed to go but wouldnt, then she did one as soon as i put a nappy on. She likes to wear knickers still but holds on until she has a nappy on again. Shes very interested if i go to the toilet, like too watch, and tells me im doing "poo" or "wee wee"

What can I do to make her confident again? She deffinatley gets it, shes a really clever kid (drives me insane! she only has to see something once and she knows how to do it!) Do I be a little more pushy? Or let her be? Not that its a big issue but nappys are a cost I could do without as im moving into my own rental again soon, she can do it, she knows whats going on but now she has this fear :(

some advice would be great :) TIA

I had a DS like this - 20m he decided he was going to TT himself. Then he decided nappies were easier, so for the next 18m he was in nappies. (Or could be we were visiting my mother and she was obsessed with "no accidents" and having DS TT'd, despite me not being worried.) Even holding it in for hours and hours until he was asking for a nappy rather than use the potty he had been sitting on prior to getting up to ask for a nappy. I also tried putting nappies on the potty so he still had the nappy feel.

He then decided he wanted to use the loo after his friend visited and used our loo, very few problems after that.

So I'd let it be the child's decision every time. Then again, we used cloth nappies so I didn't have a cost issue.

I think the best thing you can do is not to stress things have changed, I know you arent panicing but i know that I tend to get caught up in it and find myself panicing when DD has a few accidents in a few. Eg DD had 3 weeks of dry nappies at night but now she is wet every morning- did my head in for a while. Personally, I wouldnt push the issue but maybe talking lots to DD about the fact that now she is better it wont hurt anymore and when she feels ready maybe she could try the toilet again? I think you are doing great! Take it slow and she will get it. Another thing I noticed is DD went from not great at TT to, maybe 1 accident a week overnight. You are seeting the foundations and they will show themself soon :) Dont forget that when our mothers remember that we were doing x,y,z often its been glossed over in their mind. I know according to Mum I never had a bottle, a dummy etc etc but it would seem the photographic evidence suggests otherwise ;)
