My son is really into PUSA mostly because we brought him up on Caspar Babypants (check it out if you have kids, Stompy the Bear rocks). He loves Peaches, Dune Buggy, Mach 5, Volcano and 5500 Miles. He has great taste for a 5 year old, obviously.

We stopped with the night time diapers as soon as there was no overnight usage for a few days. After that point, everything went pretty smoothly, we've only had one accident since. If your kid seems to be able to reliably hold it, it's worth trying for sure!
