Two Toddlers?

So I realized yesterday that like a visit from Haley's comet, I am in the midst of what may be a once-in-a-lifetime experience. For the four weeks that we are in the middle of right now, I have two "toddlers". (Apparently, anyone between the ages of 12 months and 36 months is considered a toddler.) Ironically, one of my toddlers has acted like a preschooler for several months now and the other doesn't yet toddle, so I guess these "lines in the sand" are pretty meaningless!
