can you make the potty place fun for her with books, songs, toys, etc? can you incorporate the routine as part of the fun, letting her help pull down clothes if she's able, watch in a mirror, flush the toilet, or just sing a silly song while you do those things, etc? and practice the routine several times a day without expecting her to perform. The first step is to pt is normally to make sure LO is totally familiar and comfortable with the potty, toilet, etc and has positive feelings. Once LOs are older, they are busy and active, potty time needs to be something fun that they look forward to. That's how I pt my 2 yr old. She figured out what to do on the potty pretty quickly, it was my job to talk her into going there when I knew she needed to go.
But with BMs, yeah, I did pretty much grab her and throw her on the potty a few times... she was kinda shocked...but it worked! I would put the potty nearby in the room and make sure you can undress her quickly, normal dipes can also pull down if fastened loosely. It sounds like you are off to a good start if you can pick up on her cues!
