She's, umm, special 
And he's an only, which does NOT help!
Despite her assuring DH that she isn't going to be one of those MILs too late she has done nothing but proffer unwanted opinions, including why a car seat was a terrible idea and couldn't we just strap junior's Moses basket into the back seat, since babies should spend their time on their backs
to how I'd better not dare dress the baby in frills id its a girl. DH had to explain exactly what the car seat would look like and that they wouldn't let us leave hospital without one 
She was actually quite good about BF/FF to begin with, but as time has gone on its clear that its more about validating her FF DH and, to be quite frank, her going on about it makes me feel like she's setting me up to fail.
