Today, he wanted to know what the world tasted like.

Marshmallow creme on a cinnamon graham cracker. Mmm. It met with his approval.

The slippery, wet side of the plastic kiddie pool. Not so much. He'd make a face, but then go right back to it. Perhaps the feel is more important than the taste.

And finally, the best of all. Chocolate.
If a food is not part of his regular diet, he's always cautious. Some times he will simply wave it away. But if it looks tempting, as Daddy's chocolate bar did, then he takes what we call little sippy bites. It usually involves the barest touch to his tongue at quick intervals, like he's checking for poison or something. If it meets his approval, he'll eat it. If not, he'll push it away.
As you can see, chocolate passed his taste test. All in all, the world tasted pretty good today.
