I'm the odd one out here - at this stage I would be using pullups and have done it that way since they came on the market and it became harder to find the thick waffleweave training pants and plastic pants. I see no reason during the "toilet learning" phase to deal with messes on the floor. The trick is to treat the pullup as underwear and call them underpants. They are worn only by those in actual training. I use a diaper at naptimes and bedtime just as you would when using underwear. If they have an accident they know. If they are not aware of the sensation of actually peeing then you are starting too soon anyways. When they are consistent and going when needed on the potty - ie completely dry for a month at daycare we move to real underwear and either a pullup or diaper at naptime till again they are completely dry for a month at naptime.
In this case I would assume your child isn't quite ready and back off for a 2-3 weeks and then start the process again. Forcing an issue until they are ready just leads to frustration for everyone and child is more likely to hide the fact they have had an accident than tell you. Even in a pullup or diaper you still take your child to the potty at set times and have them try. In most cases they learn to hold it and go at the set times which makes the day much easier as you have less issues with needing to potty during story or craft time if you all try before.
