Christopher is the son of our friends, Lara and Greg. He's a year old, and a cutie. I often would worry when we'd all get together, because he is 2 years younger than Ethan, and just starting to talk, so really, would Ethan have fun.
And the best is Ethan doesn't bully Christopher in any way. He lets Christopher lead, and follows. He's very cautious and concerned about him. If Christopher wanders off, Ethan's there to tell us first, then runs over to "herd" him back to the group. They don't argue or fight over toys.
