My mother in law had issues with my intimacy with my father in law... The intimacy was the same I have with my dad.. Today my 4 year old daughter runs to her grandpa and plays with him...she has issues with that too. What could be her reason of such insecurity with me and my daughter? She has rebuked us on the matter a lot many times and my father in law is a lamb...while she's around and otherwise too.. Answers pls...

Maybe she's super old school and think that there should be a clear boundary between man and woman, regardless if their family or not. Or maybe it's a hierarchy thing -- your father in law is older and patriarch of the family and as such, has to be treated with only respect and no intimacy or closeness. If this happened to me, I'd definitely get my husband to talk to his mother. Personally I'm non confrontational and my future MIL can be quite hard headed and set in her ways so I always get my partner to talk to her when I'm annoyed or upset with her words or actions.
