Ahhhhh Toilet Training............ the one and only aspect of parenting that can bring a mom to the absolute brink of madness!!!!!!! I remember it well.
I am an avid believer in the "naked" method. It worked for my son and it recently worked for my DCB. But any method only works when the child is ready. If I have learned anything working with children there are two things that you absolutely cannot control in them.......one is their bladder and the other is their bowel. And until they are ready you might be wasting your time.
My recent 2 yo DCB was showing signs of readiness a couple of weeks ago (dry diaper, watching what the school age kids were doing) so I decided to give it a go. Unlike most providers I introduce potty training first at daycare as I find that when the mom's introduce it at home it often tends to be a power struggle.
Three days of naked time and he is fully potty trained now. (Lucky me I have laminate floors) Day and nap. I find it to be the fastest most efficient method. And even though it is a lot of work for those first few days, as you can't let them out of your sight even for a moment, it is worth it in the end and the parents are soooooo happy they don't have to do it LOL.
Not sure if this helps you at all but that's what works and has worked in my daycare so far!
