I love this! What do you do with your little one for training? I have 4 kids (14 down to 7), and after a couple of training hikes here in San Diego, quickly decided that none of them were good candidates for joining us on Whitney next week! They might be physically prepared, but none of them have the mental fortitude to keep going when the going gets rough. Is that something that is just inside a person, and if you've got it, you've got it, and if you don't - oh well?
