We have started TT'ing DD, we have been on and off for awhile, not really pressing the issue as she didn't quite seem ready. after dd's daycare teacher suggested she was ready, we thought we'd bite the bullet and give it a go.
For AGES she has loved running to the toilet and sitting on it, and associates it with wees, but always seems to go after she has done a wee. she has done a wee on the toilet, once, maybe twice at home, and one of those times she started crying and was really upset while she was doing a wee, like she felt she was doing the wrong thing?
at daycare today she had undies on, and was happily running to the toilet there, and actually did a couple wees on the toilet! she had a couple accidents, and one she was almost there but couldnt get her pants down in time, she even went and sat on the toilet when i came to pick her up.

Anyway.. fast forward to this afternoon/evening, when we came home she was holding herself like she needed to wee, so we asked her if she wanted to go to the toilet, she said she had to poo, and started crying, so we tried to calm her and say let's go to the toilet/potty! then she screamed and ran off into her room (her usual tantrum thing lol..) and came back with a nappy trying to put that on.
We said no nappies, we do our wees and poos in the toilet, like a big girl, and she went mental..
We distracted her and got her happy again, but she didn't go to the toilet or have any accidents.
She continued whinging periodically saying she hurt and holding her vagina, and we tried to ascertain what was wrong but she'd stop crying and be happy.
Anyway, i got abit over it and put a nappy on her after her saying over and over she needed a nappy because she had to poo, so i got a nappy, and then she started screaming and crying again, and seconds later did this HUGE wee in her nappy!!

I honestly have no idea what is going on? how can she seemingly be scarred with toilet training after only 1 day, and she was more than happy to go to the toilet at school, and has been for the past few weeks? (Admittedly she never does anything, but she keeps taking herself there after a wee)

I honestly have no idea what to think, or do!?
Has anyone had this, or have any suggestions on what we could do? :/
i don't want to scar her, but i also want her to know it's OK to do a wee in the toilet and not the nappy!
