M.S.
Have your in laws watch your kids!!! It is so important for your children to be with Grandma and Grandpa just as you two can use a night out. I am sure your in laws want to watch your children, they are not just "babysitters", and you are not just leaving them with "other people". They are their grandparents, that's what they are supposed to do!! It will be good for you to get out alone, your kids will have a chance to bond with grandparents and your in-laws will have a chance to be grandparents without mom and dad around!
