Do u use pull up pants diapers or tape diapers? What's the difference?

tape diapers.. diff babies have diff bums..hehe!! I find that pull ups tend to slide to the side and tape stay on better... to each mom it's own... but pull ups didn't work on my Lil ones... tried all brands still slid to the sides... I guess my Lil ones were too active when young running about lol!!! I'm expecting #3 and we're sticking to the tape diapers!! hohoho! !
