Check out that concentration.
Frequently I just cut a piece off for her to gnaw on. It keeps her busy and leaves the rest of the apple for me. We tried a little fruit muncher thing but she wouldn't use it, so eventually the apple gets real slippery and hard for her to hold onto.
After completely destroying a banana in her eagerness to get some of it, now I just give her little pieces she can pick up and eat. See, I may be a little slow but I'm figuring it out!
And now a little video for your enjoyment. That is, if you get enjoyment out of watching a little baby gnaw on an apple. I thought it was cute, but parenthood does weird things to you. :)
