My in laws are awesome very hands on grandparents who often baby sit. My mother in law dropped everything, including work for a week, when we lived two hours away and was on my doorstep within hours of DF calling her when dd was a month old. She is a saint.
My dad lives a couple of hours away and often comes to visit for the weekend, if we are in need of a babysitter he is happy to come and stay. He is quite young and loves to take the kids to the park, football, cricket, out for dinner or for sleep overs.
We are incredibly lucky.
