Potty Training...ish

We are trying some potty training in hopes that we will be complete by the time the baby comes, but Jackson has shown little to no interest. He does like to look at himself in the mirror in his Thomas the Train underwear - which stays dry for about 5 minutes. Daddy, always the multitasker, worked with Jackson on his numbers during a potty session. We are not totally discouraged because he is not even 2 1/2 yet and I have heard that sometimes boys are not ready untill closer to 3. I did a painting of my ultrasound of Sawyer. I am trying to make an effort to do everything for baby #2 that I did for Jackson. I have bought a new baby book and the makings for another belly cast.
