Park play and park essentials (not!)

Now that Grandma is here and I've recovered from whatever it was that I was having last week, I'm totally back in swing at the park!But dad and I have a major disagreement about the necessity of the sunhat.
I say it's overrated. He says that implies that we have to go back home. I say I don't care. And then we go back home. I have a feeling that I can't win this one. But that doesn't mean that I won't try. (As you can see from the picutres, Grandma is siding with dad on this one, which I find completely counter-intuitive! I thought the role of grandparents was to pamper and pamper and pamper. And say yes to whatever the grandchildren say.)
