I don't have close contact at all with my in laws and neither does my husband due to his narcissist step mother who started a smear campaign against me a few months ago (that's another story!)
Our first baby is due any day now and one of the flying monkeys has been in contact with my husband and asked when she's born, but called her by her middle name and not her first name. When my husband corrected him saying to use her first name he basically said no that's also her legal name. I know this sounds very bizarre but I've heard my in-laws do this before with one of their friends daughters to dominate them. They called her by middle name and not first and when corrected they said to us "I'll call her whatever I want to, I choose". So basically it's some weird power game.
Getting upset about it and arguing about it is what they want.. I just need someone to tell me me why it's good not to react! Reacting is what they want and they love it when we get upset, it fuels the fire. I'm just upset this game is already starting. Sorry if this isn't clear, I'm a bit tired and already annoyed by this!
