I found our HB carer really good, when dd regressed she started giving her stickers as rewards and it worked for when she was there and so did it at home too and it worked. Also at the start of TT was really kind of not commiting to it, but HB carer said just do it she is ready. So I put her in knickers, she helped choose the ones she liked and didn't like getting them wet. I spent ages reading her books while she was sitting on the toilet (potty didn't work for us, we got a special toilet ladder with a seat that dd loved). Also summer helped for us. TT I found is more work than nappies as there is a lot of accidents at the start but worth it.

The other thing I'd day is really celebrate the successes-go over the top.

Also read a toilet training guide that I will post on here if I can find it and it said don't ask them if they want to go as they often say no in that two year old way. Instead say let me know when you want to go to the toilet, I did this every hour or so and more often when I knew she needed too-that worked.
