Alex under water

Alex loves to swim in our pool and has taught himself to do all kinds of things. He'll put on this diving mask and put his face under water. I got in the pool the other day and let him take his floaties off so he could swim free and clear.
He has no fear, so I had to watch him very closely. He can only touch the bottom by the ladder because the pool is a little uneven by the filter side.
But he's doing great for teaching himself. I've never had Samantha or Alex do swimming lessons because I thought it would be a waste of money when they have a pool of their own and can practice everyday.
