I think that since it is driving distance, when the kids are small the grandparents should come to you more often. There will probably be special occasions where they will want you to come over, but for the normal visits I would say they should visit you. If it were my daughter who had a young baby and small children, I would want to help out any way I can, because when I had my two babies under two, I didn't really have any help or support at all other than my husband.
