my son is the same (except he will be 2 on 5/08). My only problem with the Easy Ups is that he won't STAND still for those diaper changes. As soon as you get his pants and diaper off he takes off running and it's hard to catch him. I personally think that 19 months is too young to potty train, then again I don't know anyone else's kids but my own.
I think that if you aren't potty training then Pull Ups probably aren't the best choice. Easy Ups (or store brand if they even exist) would probably be a better choice.
I just wrestle with the little guy because its easier to hold him down for 15 seconds to change a diaper than chase him around the house.

We use cloth diapers most of the time and I have gotten the folding and everything included in that 15 seconds. Yes, being a mom requires skill LOL
Good Luck!
