On any given night, while dinner dishes are being cleaned and the kids' stomachs are full, the screeching begins. I'm not a big fan of noise, but I do love the hour before the twins' bedtime when the kids are in fantastic moods and no more meal prep looms before me. The twins (and sometimes Claire) love making loops through the house, screeching, laughing, and being awfully cute. The video here is a perfect example of life at about 7:30pm in my household most nights - I call this the twins' "Chase Game".
I count myself as superbly lucky that I do not have kids that get overly cranky before bedtime. We have the occasional meltdown, but generally we just get giddiness at night.
