Does a MIL have any say in naming your child?

Re: Does a MIL have any say in naming your child?

Or create problems because the parents are regarded as not having respect for their elders. And I can see where they are coming from, as it’ll be nice to ask the grandparents. Another thing is that when it suits the parents they ask the grandparents to mind their children, etc, and when it suits them, they shut them out. WHY???
