I didn't put undies on DD1 until she was close to fully toilet trained. I just let her run around with a bare bum so that she could run to the potty and sit straight down without worrying about pulling her undies down. I had a newborn that was taking a long time to feed, so didn't have the time to take her to the toilet straight away all the time and she couldn't speak much so when she needed to go, she would take herself. I would sit her on the potty every hour or so if she hadn't done a wee for a while too. We had plenty of accidents and I dealt with them similar to how you are dealing with them. She was fully TT day and night at 22 months so I think that technique worked but I'm sure DD2 will be different! If you are letting her run around with just undies on now, maybe try no undies when you are at home so it's a bit easier for her to take herself to the potty. Also, rather than asking her if she needs to go, physically sit her on the potty every now and then and see if that makes a difference. It takes them a little while to associate the two. I have no idea whether that will work for your DD, but just suggesting what we did It sounds like you are handling it perfectly!
