Double baby shower

Teaka
I need some other new mommies input. My sister in law is 2 weeks behind me. My mother in law asked today if she could throw me and my sister in law, jessica, a baby shower together for just her side (my husbands) of the family. My family and friends would not be included. My mom already planned on throwing me one in may including his family in it. My mother in laws reasoning is so all the relatives don't have to go to 2 showers back to back. We would have separate cakes and gift tables though. I talked to my husband and he wasn't for the idea of a double shower. What do you soon to be moms think?
