One day? One day. One day?
Am I the only one that thinks that's nuts?
If she doesn't do what the book says she's supposed to do, what does that mean? She failed? You failed? No, it means NOTHING. Do yourself a favor and throw that book out the window. Let you daughter tell you when she's ready. I think potty training is the same as eating solids, weaning, sleeping alone, everything else. It's going to be different with each child. You can have 10 children and they will all do these things at different ages and at different levels of ease.
There are so many things to take into consideration. Have you had an "open door" policy so she can witness what actually happens in the bathroom? Is she showing signs of readiness?
If you start potty training before your child is biologically and emotionally ready, you're both going to become frustrated and upset. It will also drag out the process because it's likely to turn into a battle of wills.
My just-turned-two year old uses the potty every day (and started this at 18 months). But not all day. I know a kid older than him that doesn't even know what's supposed to happen in the bathroom. I know another kid, almost in kindergarten, that still uses pull-ups. The whole process is just that, a process, and can take up to a year to become the new routine. So don't be upset if your daughter needs more time or the one day technique doesn't work for you.
