Is there food at all at the museum? Even a vending machine and sitting area to eat? Can I bring snacks? I'm just thinking about snack time for my little one.

There isnt really a sitting area designated for food as part of general admission but they do have rooms for parties and spaces to sit down throughout the museum. Also they have composting on site so they must expect food.

There is a souvenir shop with some snacks in it, you can bring your own snacks

I always take my own no matter where i go

I always pack my own snacks. There are some limited options at the gift shop if you're in a pinch with a hungry little one.
