I'm always amazed that my 'little monsters' looked so sweet and adorable in their PJ's and completely sacked out...but when the sun came up they were back at it. LOL, the grandparents were always quick to give them back and yet quick to miss them when they were gone.
You are in a very sweet season of life. I miss mine being little; teenagers are less easy to deal with and yet so much more important to parent. [sigh] Can't freeze them at that age but certainly enjoyed it while they were there...
Having all girls (1 great grand son 100 miles away) it is pretty sweet. They can be so loving/caring/cute/cudely and at the snap of a finger go straight Zombie Woof
