Congrats on your first grandson, the fun has begun. We have Logan, 23 months old now, and are expecting our 2nd grandchild (don't know the sex) in April.
What a joy Logan is, as we watch him while his Mom teaches at our high school. I feel 25 years younger, enjoy every minute of our time with him. It is so much fun with a grandchild, as you don't have the other pressures of being the parent, only the joy!
Friday, as Logan was playing with his Thomas trains, he called me, " Nana, I love you a whole bunch". (I always say that to him, never expecting him to return it!) My heart flipped!
Life is good, enjoy your bundle of joy.
