C.,
Your Mom is very lucky to have you. A massage would be nice along with the day spa idea but how about if you mix it up and have a "date" with your Mom to help her celebrate her big day? If you have any sisters that could come along, that would make it an even more enjoyable day. Years ago, my Sister took my Mom to a B&B for her birthday and she still talks about it to this day. The one thing she adds though was how nice it would have been to have had both her girls there. Her birthday is next month and we are planning a very special girls weekend for her. My sister and I are having fun planning it and can't wait to hear her excitement on her big day! Oh - it's a bonus for me and my husband as well - Daddy gets some quality time with our little Princess and I get a break!
Good luck!
