Controlling mother in law

So I'm not far along in my pregnancy and I'm already becoming worried that my mother in law is going to be a complete control freak once my baby is born. It's her first grandchild and I understand she's excited but she's already mentioned something along the lines of, "your baby's gonna be sleeping here with us" and "don't you think your gonna raise that baby to pee in his diaper till he's 3, all of my children were trained by one years old. If you're not going to train him by one than I will." Seriously???! Should I be worried already
