The first time through, he got stuck and shouted for my help. I gave it, and he continued on.

The second time through I was there waiting for him, and reached out to give him a leg up before he could get upset. I followed beside him the next few times, ready to push or pull as soon as he asked.

But before long, he had figured out how to climb over that steep spot on his own, and thereafter he didn't need me anymore.

But then he turned and beckoned me to follow him in. "Daddy, come on!" he shouted. "I want you!"

It's nice to be wanted.
