Baby shower... and MIL.. foreseen drama..

Gi

My dad is throwing our baby shower (my mom passed away 11 years ago). We didn't ask him to, but he is, and we are incredibly thankful. The only thing I asked him in regards to the shower was no children. I personally don't think a shower is a place for kids. Anywho, he didn't care. On the invites, he specified it would be for adults only.

A week after the invites went out, my MIL told us about the invites and told us that she reached out to my dad about having our niece (her only current granddaughter) there.... (8yrs old)....

I don't think she realized that it was our decision to not have kids.. so she starts going on and on about why she should be there.... even made a point to mention that she would just be hanging by me the whole time. (Exactly what I want to avoid). I love this little girl, however, I don't want ANY kids there. Nothing against her. My hubby is going back and forth on the decision. (Ultimately, it's up to us). But he thinks it will cause drama if she can't come...

Is it crazy for me to think that the whole thing is just rude..? I know in the end if she's there, it won't bother me all that much (or so I hope..) but I just think it's rude to make us feel guilty for her not being invited ..? There will be no other kids there, it's 4 hours long, etc.. My dad was also thrown off by my MIL asking and not his sister.... and thought it was rude considering the invitation specified no kids. He was going to reply and say that it wouldn't be fair to everyone else and leave it at that, but I told him we would decide. Sadly, we knew this would come up and had already started the discussion...

But why is she so concerned, I don't know..? Shouldn't my MIL want to celebrate her new grandchild....

I'm going back and forth, but really just want to say no kids allowed means no kids allowed.....

Opinions welcome =) but I really prefer to avoid the opinions regarding the general idea that it's a no kids shower!

Maybe I should also mention that my SIL (nieces mother) ended up leaving our wedding shower crying because she wasn't involved or something, so I already have some sour thoughts ... but am trying to stay unbiased...
