Potty Humor

We are working on the potty training thing. Well actually Grandma Carol and Nik are working on the potty training thing and I support in the evenings and weekends. We have got him to go pee in the potty chair 3 times now, we had to catch him in the act.
I got home from work one day last week and was greeted with a bare baby bum. Raivis was telling me that he went potty in the potty chair and was very excited, then he looks at me and says:
"Potty gound."
"No, potty on the ground, go potty in the potty chair."
"Potty shoe"
"No potty on the shoe, potty in the potty chair."
Then with a naughty look in his eye, "Potty mommy." (meaning he was going to go potty on me)
Oh dear, I think we have our hands full with this one :)
