We tried the 3 day method over the weekend and weren't very successful. After 2 days she was still wetting her undies like every 5 minutes, and when I asked her if she was wet she'd say "No" even though she was. On day 3 she was sick so I decided to just put her back in diapers and not push it.
Just fyi....She's 27 months, can pull down her pants, tells me when she poops (but not pee), watches me on the potty, and has peed on it 2x before. She also went like 2 drops on day 4.
I think now I'm just going to try to have her sit on the potty after waking up and before bath time (on days I'm home) and try more diaper free times over weekends. I was really hoping the 3 day thing would work, since I'm WOHM and it's hard for me to take time off, but I think we'll just have to take our time.
