Ideas to solve a fear of toilets outside the home?

DD is basically toilet trained, but will not use a toilet outside home. At home she was mainly using potty but has used the big toilet (with a seat) for the last week. She sat on a little toilet in a shopping center change room once and that was fine, but now she just says she is scared of other toilets - including the little one at daycare, the one at playgroup which has a little seat etc. This morning at daycare I took her to toilet, her doll went first and then I said it was her turn and she happily sat on it (didn't do anything as had just been at home) but when picked her up she had refused to sit on it again saying it is too big (is smaller than ours at home). So at daycare she is in nappies (they don't have a potty), and when we go out she is in pullups - often she will wait till we are home to go but depends how long we are out, if she can't wait she will tell us and then wee in her pull ups. Poo's she always seem to wait to be at home. Overnight she is dry 6 out of 7 nights and goes as soon as she is up in the morning.

Do I just need to wait it out? Should I take her out of pull ups and just in knickers when we are out and put up with the accidents?

I don't think any other children in her room at daycare are using the toilet yet, or am sure she would be keen to copy them (she is 27 months old), daycare suggested the tactic we tried this morning and will also ask them for further ideas.

My Ds3 had a fear of toilets around that age. I can't remember what we did but eventually he started using them. He won't flush them though even now and he is 6. Can you take a potty to day care for her? Hopefully they will allow that

Maybe ask her why she is scared of other toilets . It could be because its just simply different. If you aren't bothered by her wetting her pull ups then I wouldn't stress about it. Or maybe not use the pull ups for a short shopping trip and see if she realises she has no option but to use the toilets available kwim?

Thanks for the reply good to hear it isn't unheard of. We had a small triumph today we went to the zoo, and I took the seat we use on the toilet at home with us, and she asked to go to toilet and actually used the toilets there with the seat (often she asks to go but won't use it when we get there when out) - will have to see whether can continue doing that, if so I will get one of those fold up seats to use.
