Jeremy and I are anticipating potty training Evan will be a lenghthy process. Obstacles abound--communication issues, the night-time tube feeding (I don't think it would be possible for him to stay dry at night until he's not having 500 mL of liquid pumped through him). Having said that, I don't want to delay starting simply because we think he will be in diapers longer than a typical child.
I bought Evan a potty chair today. I have had my eye on this particular model for a while now--I like that it has a nice, broad base that will help Evan feel secure sitting on it, and that with the top down it can be used as a step-stool (it can hold up to 300 lbs!).
(Although this isn't meant to be a sales pitch, if any fellow moms out there are interested go to www.booninc.com. I found the "Potty Bench" at Babies-R-Us, but per the webpage Target and various baby boutiques carry it also).
Here are some pictures of Evan's first time sitting on the potty chair--the lid is down and his diaper is on. Baby steps--he absolutely would NOT sit on it with his diaper off!
Evan was more interested in opening and closing the lid than actually being on the potty. But all in all, it was a good first experience.
