I remember diaper pins and cloth diapers, I tried them for a brief time. I remember sticky tabbed diapers, they were great, but they couldn't be repositioned or adjusted without tearing apart.
Velcro (or whatever that is they used now) is awesome!
One problem I'm having lately though is that even an 18 month old can loosen up those velcro tabs. She prefers to be naked apparently. I put her down for a nap yesterday in a diaper and t-shirt (who wants to sleep in jeans), and sometime between awake and asleep she apparently decided to sleep naked. John came to get me to show me the little miss- sound asleep with her naked bottom up in the air. We let her sleep!
Gotta run and re-diaper my baby!
