After buying every kind of diaper known to man, the day is coming in the near future when buying diapers will be a thing of the past. If you don't buy diapers, please note that there are different kinds that you need:
My boy is wearing big boy underwear that he picked out last weekend - MICKEY MOUSE! One day this past week, he went the ENTIRE DAY in the same pair. Picking him up in preschool wearing the same outfit that I dropped him off in is a treat. Other days, you are handed multiple plastic bags of outfits and underwear with little notes on the outside telling you what happened. I seem to live for laundry these days.
Wearing underwear is addictive. My son now cries if I put a pull-up on him instead of his big boy underwear. It's a new sensation of no bulk between this legs. Here's the trick - he doesn't like to stop playing to go to the bathroom. That's our problem at home. We are working on a set bathroom schedule.
It's still a whole new world for us.
