Post-script

With a whole lot more confidence, Teddy kept jumping in the pool, swimming around, until he decided he was going to try and get to me even though I was a long way away. He made it about half-way and decided to go back. As he was turning, he ran out of air, came up, took a breath and kept going. Half-way back, he ran out of air again, took a second breath and made it back to the steps from where he had left. Needless to say that put a smile on my face. He's not completely water-safe yet, but he sure is getting there.
