my 2 cents(and my kids are 8 and 6)
my son NEVER wore pullups of anysort, was in those thick undy things (kinda like underwear) at 18 months, was fully potty trained by 2 an half - i had a washer and dryer with him hence the thick undy things
my daughter @ 18 months i stopped buying diapers and started with pullups(whatever kind i could afford, usually store brand at about $8 a week) when she was 2 she was fully potty trained, except was still having accidents until she turned 3 at night, if i would have had a washer and dryer i think my daughter would have been potty trained sooner as my son wore the undy things, my daughter didnt, yet she had accidents at night for a year longer then my son did and all she wore was pullups
