I was beginning to wonder - my son turns 30 in September. Not having any grandkids to entertain surely makes me miss all the fun times we had. Too bad you can't just freeze them at about age 8 for a few years.
One thing for sure, time spent with your children is so very precious. No matter how much time you spend together, how many things you are involved in with them - years later you still look back with fond memories but also with tears of longing to have done even more.
