Awww, congratulation, I can remember when my mum was a first time nan to my brothers offspring, she was walking on air for days. The granchildren are her life now and they range from 15 yr old Grand-daughter to our DS3 who is 4 months.
Enjoy it, it's will be great fun being a young nan.
Wow, big news Nanadoormat, congratulations! You can't give up the mini skirts, I've only just started wearing them again because of you, and I'm 37! The grandchildren will need someone to show them how it should be done anyway .
