Sara decided pretty quick once we got into the zoo, that she wanted snacks.  And I noticed signs that said no food in the zoo. SO, I asked Sara to sit down in her stroller to eat.  This is what she did:

And when I asked her to sit in her stoller again, she scooted even further away from the stroller. But she did understand that I wanted her to sit down.  So funny.  She ended up just carrying her snacks and she never got back in her stroller.
