For the first time! My son, who will be 22 next month, and his 20 year old girlfriend are expecting. I had mixed feelings at first, but I've had a couple of days to let it sink in and I'm getting excited about it. What's done is done and we will make the best of it. His girlfriends mother has been my best friend for 26 years. These two have known each other all their lives, always said each other was their best friend. It was kind of weird for us when they first started dating and then moved in together. My son hasn't always been the most responsible person in the past but she seems to have influenced him in a good way, he's much more mature lately. I get to share a grandbaby with my best friend! We are going to be awesome Grandmas!!!!
