Trying to deal with the mother in law...

My MIL is driving me crazy, she already got a crib, nursery furniture, and tons of clothes for my baby. Which would fine if I asked her or if she asked me. And when I confronted her about it she just lets me know that I'm ungrateful. I'm just upset that I feel like I get to do all the hard parts of pregnancy (16 weeks and still throwing up all the time) and none of the fun stuff, like picking out a freaking crib. And she keeps telling me that she thinks I should move in with her so she can take care of my baby for me. Not cool , and she acts like my husband and I don't already have a place to live. And on top of that she keeps calling her grand baby "her baby". It is driving me crazy
