So I have a pretty serious question? I might be crazy but who knows. okay, so my MIL has this friend who got her tubes untied. she's tried twice to have a baby and lost it both times. (she already has 2 kids thats been taken away, very sketchy drug history, and is in her early 50s) My MIL invited us to her husband's birthday party and this girl told my MIL that she didn't want us there bc I was still pregnant and if she had her way I wouldn't be by the time I left. creepy right?! well my son is here now and my MIL insist on babysitting him. which would be okay if she didn't want to bring this crazy lady over to her house while he is there. I'm honestly kinda scared she's gonna take my baby 😦 Am I crazy?!
