Good snacks for 9 m/o baby for when we're out in public?

What's also nice is graham crackers. Kids adore the flavors, and they break down to be held in little hands, but they don't break off easily by little kids until they can chew very well. They also get gummy and fall apart, but are easily swallowed. I'm sure you know that, lol, everyone has had a graham cracker.
