We're potty training this weekend using the 3 day method (with a few modifications). My LO is 22 months, highly verbal, knows when she needs to poop but does struggle with knowing when she needs to pee and how to release the pee. For about 6 weeks she has been very interested in the potty and asks to go throughout the day although it typically appears that she asks to go AFTER she has wet her diaper and wants a change. She goes to daycare and they take her to the potty about hourly. She's had a couple of pees and poops in the potty before this weekend.

We have about 3 hours left in day 2. She pooped twice in the potty without an accident. For pee though, she has mostly peed on the floor. We've learnt her pee signs but she won't release on the potty (most accidents right next to the toilet) or she'll only try for a few seconds and then pee on floor soon after. the successes we've had is rushing to get her on when we notice the potty dance.
Advice? Commiseration? How long did it take your LO to learn to release on the potty?
