Good informational book
If your trying to potty train get this book. Read, ponder and reread. Then go for it. I was really surpised how fast my little one took to it. I will say, I stubbled beacuse I didn't stick with it through they first day. after rereading and realizing you have to be methodical. The second day was bam!!! A little old pro..
It can be done in one day, but it must be methodical.. NO distractions of "i'll just do this while i'm waiting..." stict to it and you will be amazed. also use small treats that are a bit or smaller. think two m&m's
