I'm sorry you have to go through this with your mil. It sucks I know!
Mine are still like that Now that I'm a SAHM mine call me 3 times a day to make sure their lil buddy is okay!! If I don't pick up the phone they will call DH and my parents to find out where I am. I like WTF I'm an adult and I don't have to tell you when I want to do something.
