Suggestions?
Mine is 20 months and will take his diaper off and pee on the kitchen floor. I wanted to put down newspaper, but you konw that idea didn't get much love around here

I'm thinking 2 years old, to start trianing?
Considering i have a girl i really don't know exactly the answer for you but i do believe 20 months is early when it comes to both sexes. They say girls are easier than boys and Taylor was COMPLETELY daytime potty trained at 2 1/2 but wears a pullup at night and DOES pee in that thing occasionally.
The newspaper idea is funny but i can see where maybe the wifey didn't like it too much. Just let him watch you when you go and believe me, they do learn and will not be going to the prom in a diaper...it's a long process that parents need to be patient with.
Hope that helps.

PS. While we are on the subject of children, anyone have an idea how to get the dang binkie out of her mouth (she turned 3 in March) and how to get the precious OUT OF OUR BED at night?
