Not at the same time, of course.
We have finally found a way to get him to drink cow's milk: a big boy cup (glass ... former jelly jar ... whatever).
And also, he now has a potty chair. It's dry, but I'm just insane enough to believe that he can be potty trained by 17 months. That's the goal. Stop being negative. Look at that smile and BELIEVE.
And also, he LOVES Dad's lasagna (as does his mother).
We're happy.
