Color-code diapers to distinguish different sizes at a glance
Christel's simple and practical hack for parents who have more than one kid in diapers:
When my son was a newborn it was easy to tell his diapers apart from his toddler sister's -- his were so very tiny, it was obvious whose diapers I had and how many of each, whether in my diaper bag or worse, in the basket of the stroller where I was in the habit of tossing handfuls of supplies as I dashed out the door. Now that he's bigger the differences aren't so obvious, especially once the diapers have had a chance to rattle around in the aforementioned clutter zones and get all wrinkled and expanded. Sure, the diaper companies print the size on the diapers, but always in what seems to be very faint ink and in seemingly random places (it's on the front right waistband on the smaller diapers, but on the back of the bigger ones). Plus who wants to do inventory by pulling every diaper out of the bag or basket and finding the size spot, much less looking for the right size when you've got a messy kid?
My new solution is this: the first thing I do when I open a new pack of diapers is grab one of my permanent markers [Sharpie love! -- Ed.] and run the marker up and down the bottom crease of the diapers a few times, using a different color for my son and my daughter (I confess I went for the obvious pink and blue). The diapers are always packed so tightly in the wrapper that it's easy to mark up several dozen in a matter of seconds, and now I can store them anywhere, upside down with that colored seam facing up, and know exactly whose I've got and how many of each.
