Speaking as a 60 year old grannie, with 3 grown and married children, and 7 grandkids, it does get better. I can remember how relieved dh and I were when the last of ours married and moved out. Unfortunately, they keep coming back home! Both of my girls had to move back in for short periods, and one of them now has a home right next door. I really appreciate having her so close, now that I've gotten older and more decrepit, but it's always a relief at the end of the day when everyone goes home, and I have my solitude again!
Hugs,
