This is the boy who has always run AWAY from the waves at the beach, the child who preferred to lounge on the side of the pool and was never the least bit interested in entering the water.
We decided not to push him. Surely, someday he would be ready to "jump in" on his own.
Sure enough, two years ago he discovered the joy of jumping in the ocean waves. Before long we had a hard time getting him OUT of the water.
