I have to say this was one of the most unique things we did while in Kenya. We got to feed giraffes. We went to the Giraffe Centre (read more about it here), just outside of Nairobi.
At first Sam wasn't that into feeding them but we... encouraged... him to try it and he thought it was okay. He mostly wanted to watch though.
Rachel was also a little hesitant but then she got brave. And then she made friends with a baby giraffe and she was all about feeding him (or her!).
...but I did!!! More than once, in fact!
