I may have a problem.

Okay so I had a miscarriage about 7 months ago. My sister in law is about to start trying to conceive. My problem is our mother in law has always shown favoritism towards her and my husbands brother so I’m afraid that if she has a baby before my husband and I, she will treat that baby better. I’m happy they are going to try and that part doesn’t bother me. It’s if they have a baby before us then I can pretty much guarantee our baby wouldn’t get as much attention or love from our mother in law. I’m kinda worried for our future child because I don’t want him/her to feel not as important.

Am I wrong for feeling this way?
