When my daughter was an infant she used to bawl inconsolably when I would play arco.
I used to like to think that it was the volume that bothered her, or perhaps that it was that I was doing something other than paying attention to her.
On the other hand, maybe she was trying to tell me something much more fundamental about my playing...
Anyway, really sweet that you have integrated your daughter into your musical life...thanks again for sharing it.
