Hi M., First of all let me say that I am happy to hear he is 19 months and you want to get him his first potty Chair, and not waiting until he is 2 or 3 so kudos to you mom. Any potty chairs made from fisher price, little tikes, the one I have for my daycare baby's is Baby Connections, I have the foot stool and potty chair that match, and it has a litle handle that when you push it down it makes a flushing sound, and say's all done. Here's a tid bit of advice, let your son sit on the potty chair while watching something he really enjoys, my first born (a son) when he was 19 months I started potty training him, one of the easiest things I've ever done, anyway he liked to watch the price is right, so I had him sit on his potty while he watched it, and it's an hour long show, but he always sits and watches it anyway so hay it worked during that hour something was bound to happen, and the iceing on the cake was, at 19 months he started reconixing his numbers by watching the price is right, it was veru educational for him, by 20 months he was completely trained and was going on his own. Hooe this helps
