High frequency

They say that right before earthquakes livestock tend to get universally agitated, birds fly en mass from the trees, and the cows all stand up. Perhaps they're all just supremely sensitive to slight ground tremors, or just have some strange sixth sense about these things. Either way, I think our daughter has developed a similar skill.

Mia and her BFF have somehow developed their own form of sub-sonic communication, and are on the same sleeping (or in some cases, not-really-so-much-with-the-sleeping) schedule. They could be separated by miles and lead walls, and still melt down at exactly the same time. When Isabella sleeps, Mia sleeps. When Mia is hungry, Isabella is hungry. Perhaps later on, when she can explain this all to us it'll mark a leap forward for our society, but right now it makes for a neat party trick.
