Usually he chooses a book or his giraffe to take in the pram. The other day he insisted on taking his uke! Held onto it for the whole walk. The next day he insisted on bringing our neighbour's dust brush.
I went along to a ukelele group in West End this afternoon. It was super fun and totally at my level (ie total beginner!), and he played happily for the HOUR with a couple of 'big' girls in the kiddie space, a few metres away. I really did not imagine he would make it THAT easy for me! Definitely going back next week.
