MIL Advice needed!

McCarron20

So I'm not really crazy about my MIL.  When my Husband and I got married, we moved to my home state, which is hours away from their home and she's been rude and mean to me ever since.  My Husband and I are due in 7 weeks and she's already said her and her husband will be staying with us for at least a week.  I'm fine with them staying while I'm in the hospital, but I think I'm going to need a couple of days with just my husband and baby when we get out of the hospital.  Is that bad that I don't want them there?  It would be good if they were helpful, but she doesn't cook or clean and she's extremely loud and opinionated.  Not to mention they just bought a puppy.  I love dogs, we have one ourselves, but puppies are high energy and get into trouble.  Any suggestions?
