I went whole hog when we started TT. I started putting them on the toilet every half hour after asking if they needed to go. It seems like a lot but it was worth it. If there was any conflict with sitting on the toilet I wouldn't push it but most of the time they were happy to sit there. Eventually I pushed it out to every hour and then could do two hours. I never went longer than two hours because in the beginning that's how long they could hold it for (my girls were 19 months and 17 months old respectively when we started). After two months, they were fully TT day and night. It only took a couple of weeks though before the accidents were rare. I did do it with them running around in the nude right at the beginning but that was because they hadn't got the hang of pulling their undies down. I'm not sure if the technique we used would work with a three year old but I do think that you should go straight to it 100% otherwise it becomes confusing and she may start to use it as a form of control seeing as she's a bit older. Just make sure that daycare and your other carers know what is happening and what your plan is so that they can be consistent. Just take it easy and be as relaxed as possible. Be ready for plenty of accidents and stay calm when it happens. Also, be prepared for everything to be going really well, and then one day it seems she has gone backwards. Sometimes, they just have a bad day. Don't be discouraged good luck with it all xx
