TwiceToddlers Not "Toddlers" Anymore

So, with my twins now in kindergarten, they are no longer toddlers. Now, I am wondering what name I can use behind "Twice". When my twins were babies, I called them "TwiceBabies". When they became toddlers, I gave them the name, "TwiceToddlers". Now, I would like some input into what new name I can add to the end of "Twice".

Looking for suggestions...Anyone who comes up with a good name will get a FREE Rhinestone Tank Top, something like one of these. Of course, when whatever saying you want on it.
