If the T-Rex from Jurassic Park was attacking, how would I keep my wild 3-yr.-old still?

Since the movie taught us that her visual acuity is based on movement, how would you keep a rambunctious preschooler quiet and still to protect your family?

Similarly, if you’ve never seen Jurassic Park, how would you keep a small kid quiet like at the end of The Sound of Music when the Nazis are shining their lights inside the mausoleum trying to find the Von Trapps?

I think my son would give us away and we’d all be dead. How would you manage to survive? In the T-Rex situation, we might be able to sacrifice my son to save the rest of my family, but this probably wouldn’t work for the Nazis. Just kidding- I’d sacrifice myself… probably.

In a life and death situation, how would you keep a crazy kid quiet?
