Thanks everyone for the lovely comments! It seems funny that the oldest 2 (the redheads in the photo) are the latest additions. My son and his husband are adopting them. They only joined our family last November but it seems like they've always been with us!
Sharon - I'm jealous! I think we're very close in age ... I'll be 54 in a few weeks, and I have to work another 11 years! Ah well c'est la vie! xx
