Little rockstar now takes his uke along to the cafe when we go to watch Tim play nursery rhymes on Friday mornings. We even take a spare to share (i.e. he doesn't like to share, and the spare means that he doesn't always have to...). Not much actual strumming happens in public, but he's increasingly making quite a beautiful sound when he plays at home.
The first time I was able to make it along to my ukulele group in about 6 weeks, almost everyone else was unable. Even the venue was unavailable! Luckily my sis and my son were on hand to boost the numbers, so we found a new venue and had a little jam anyway. Gosh it's fun - I really need to get around to playing at home once in a while!
