Anyone else having this problem?

Ok so I spoke with my FH last night. He told me he ran into his mom on his way home from work to stop and pick up some groceries. I seem to be having a bit of an issue with my soon to be aunt-in-law. Here's the back story (kinda long):

FH's aunt is obsessed with having her grandkids (or FH's second cousins) at our wedding. Not just ours bc she's done this to other cousins in the past, including one that FH and I went to this past December. And it only seems to be these specific two little children that she wants there. So FH's other aunt warned us when we got engaged that she was going to push this. Didn't think much of it at the time but we decided to establish a boundary there early by saying we do not want little kids at the wedding and its not the place for them.

So the aunt didn't take the hint and was then fighting with my soon to be FIL, her own brother! and they werent speaking for some time. I got upset bc this is not supposed to be a time for people fighting and this is our decision not my FILs. My FIL told me not to worry about it as did my MIL. For a while we heard nothing. FH's aunt actually called me last night and spoke to me for over an hour, not once mentioning kids at the wedding so I had assumed this was all water under the bridge. Even when she was fighting with my FIL, she had only spoken to me and FH about it once.

Anyways, MIL, my mom, my MOH, and bridesmaids are all working on my bridal shower. That is all I know. So apparently FH's aunt called my MIL the other day and told her that we should invite FH's cousins little kids to the shower. My MIL was like why? thats not necessary at all. FH's aunt proceeded to say 'well so they can see how everyone interacts that way they will be comfortable at the wedding'. Apparently MIL stood up for not just FH but me as well and told her she was very rude and this was not up for discussion as we already established that we're not having kids at our wedding. This is supposed to be me and FH's day. Meanwhile, I know people with great kids and my own cousins have children that I am not inviting. I feel like this aunt is trying to turn this into a three ring circus and she's getting really pushy but I can't say anything bc that would mean throwing my MIL under the bus for telling me. Then I felt like an idiot that I confided in FH's aunt by talking about all my personal stuff with her bc I thought I could trust her. Plus she said things to me on the phone last night that made me go '***?' so now I just feel like I am being used. Anyone else having some kind of issue like this with pushy family members???

Seriously I've got enough going on with work, school, taking care of my puppy and FH's dog, trying to plan a wedding, and dealing with drama with my father. This is not something extra that I need. Totally unnecessary!! UGH!

What about talking to the grandkids parents?

I would tell them you just wanted to clear up some confusion, the kids are not invited to the bridal shower and the wedding. You just wanted to give them a heads up so they can plan accordingly.

We did tell them and the cousins don't seem to be having an issue with it. It just seems like FH's aunt is doing this. I have absolutely no idea why and it's frustrating and unnecessary

Re: Anyone else having this problem?

Stick to your decision. It is definitely a pattern for her. Some people are just so pushy and kudos to your in-laws for not caving in.
