Tin whistler in the making?
My 13 month old son was playing quietly with some toys, so I got a tin whistle out and started playing “Tarbolton”. He immediately crawled over to me, took the whistle out of my hands, put the mouthpiece into his mouth and began going “ooo-ooo-ooo” and smiling gummily as if to say “anything you can do, Daddy”.
I had to take it off him when he started bashing the top of the coffee table with it, though. It’s only an Oak - the whistle, that is; I have no idea what the coffee table’s made of.
