My baby entered a phase this week that all my kids have gone through. When she gets bored with eating something, I can coax a few more bites from her if I let her eat it off a fork. Maybe its the texture, maybe its just something new. But I bet there is something in her little mind that is like "oooh, its sharp! I pokes! I want it!"
Its the same attraction we all have to fire, the love we have for fireworks, swimming, etc. We know there is a little bit of danger involved and for some reason we are drawn to it.
I saw this TED talk recently: 5 dangerous things you should let your kids do.
The speaker actually has a book with 50 dangerous things, which I would be interested in seeing. Now, I dont let my kids go crazy. I have a no football, no boxing rule. I just worked too hard on those brains to see them get bruised up. But I do let my kids build things, burn things and try out stuff. My husband lets them do even more.
What I loved about his talk was that in doing the "dangerous" things, kids learn about limits. They learn how close to fire feels good and how close will hurt you. They learn how to hold a drill so the screw goes in and doesn't fly around ( a lesson I am still learning) They learn where their limits are and what they can do. They learn they are strong and smart. All good stuff.
