Roy Thomson Hall (photo by Mimi Choi) Since becoming a mommy I find that there are days when I crave doing adult things so my life isn't totally about diapers, baby programming and baby music. But finding a babysitter for some of us doesn't come easy and can be very expensive; yet every once in awhile it's important that we spend the money and make the effort. On November 18th I took Mia, my two-year-old, and my 12-year-old niece to see a children's concert at Roy Thomson Hall.
