I never yelled when cleaning up an accident, we just cleaned it up and moved on a simple uh oh, next time we better get to the potty fast, seemed to work wonders
We never used pull ups, except at night and that was brief, like three months or less
I would take our children potty pretty much every thirty minutes for the first two days, they seemed to start telling me about day three
I never used a "little potty", our children use the big potty, yes that meant I had to be there all the time, every time for a while, but it also meant less work, no cleaning little training potties, and no retraining bigger children to use the real potty
I tried to never leave our children in wet diapers, very expensive, but worth it, and this seemed to heighten their awareness, all our children but one were telling me when they went potty by about 18 months, so we could change them, this was also around the time, they were all put on the potty to sit and read or just explore it
We have four bathrooms, you might think that privacy would not be an issue, I never recall since having children being alone in the bathroom, I think this has been beneficial, they saw mommy and daddy in the bathroom so there was never any fear associated with the potty
I never went from under wear to diapers, and back and forth, we went to under wear and that was it, no going back, no wavering
Of course every family is different, and therefore these strategies worked for us, not everyone, hope they help!
