I didn't know whether to put this under Potty or Gear, so please feel free to move it if it would be appropriate elsewhere.

We've looking to get E a potty chair...the separate kind, not the one you put over your own toilet. E gets a lot of diaper-free time (thank you recurrent yeast infections) and as a result I'm constantly cleaning up after him. Over the past few days he's starting cleaning up his own pee (or at least finding a towel and covering it or a wipe and trying to wipe it up). It's kind of adorable, and got me thinking that maybe it wouldn't be a bad time to start introducing him to a potty chair. I'm not trying to potty train him now, of course, just introduce him to it (and if he'll start peeing in it, huge bonus!)

ANYWAY, if you've bought a chair, which do you recommend, particularly if you have a DS?
