Argghhhh !

Nano went for his swim lesson yesterday afternoon. He got into his silly tyke moods due to the lack of sleep. (Didn't nap in his centre !). He just would not cooperate with the instructor at all ! This time, at least the instructor decided to give him a time-out and sat him on the edge of the pool along with his swim buddy, Joshua, who was also in the same boat. Is 4 too young an age to start to learn ?
