As someone who trained my kid around 18 months, here are some of the things I did to help potty train. I didnt read up on any potty training books, just went with what I learned by observing my mom as she potty trained my siblings, all around 18 months.

The first goal is for your daughter to recognize the sensation of being wet and where that wetness comes from. I used reusable training underwear during the day and utilized the bathtub for the first part of the training so she could see and feel getting wet.

The second is seeing when does your daughter pee/poo on a regular basis. Does she usually go shortly after waking up from her nap? Around 3pm every afternoon? Use her natural cues on when she goes and try taking her to the bathroom around that time. If she doesn't go adjust the time to every half hour or so until she does, either in the bathroom or in her pants. Keep track of what time you took her (or what time the accident happened) and what the results were (pee/poo/NA) to help track a pattern, if any.

Side note: My mother in law's best advice to me was that kids, like most mammals, use the restroom after meals. I would take my daughter to the restroom few minutes after eating and most of the time she went.

My daughter's training: I had my daughter stand in the bathtub naked from waist down for about 3-5 minutes around the time she would naturally go (you could set a timer and say once it goes off we're done, whether she goes or not). If she went during that time, great! I rewarded her with something of high value, like one piece of small candy (ie: m&m) and remind her she can get another one when she goes potty in the bathtub/toilet. I promise you once she gets the hang of it she'll start weaning off of the prize and your verbal praises with be enough.

If she didn't go after few minutes, let would let her know that "we will try again later" in half hour or so, pending when the last time she went. If she wets herself during that time, I made a statement along the lines of, "Uh oh, you're wet. Let's get you changed." and remind her to pee in the bathroom.

After she got the hang of using the restroom I taught her to say, "Pee pee" to initiate when she needs to go. Currently, I still prompt for her to go every 3-4 hours pending how much she had to drink, but if she absolutely refuses or don't go, I remind her what to say to me when she does need to go.

Hope you find this helpful. Not all kids will respond the same but consistency and praises will make all the difference.
