Dear God my parents drive me nuts! Loooooong

My mom and i are trying to plan a 'meet the baby' party/shower for my sister and Ezra during the week of Memorial Day back home in NM. I'd prefer to plan it all myself and let my mom/Ezra's grandma relax and enjoy the party as well. But she wants to be involved and help out, which i understand. The only problem is...she doesn't know how! She gets overwhelmed and confused! She's flip flopping on locations!!

First she wanted to do it at her house. But my brother just moved back home and his stuff is everywhere. And we don't have enough chairs. And she's constantly doing work to the house so that a 6 inch strip of rug is missing from the front room where people and kids would be walking. Plus, we'd have to clean up afterwards. I want to do it at the local Uno's cuz they have a secluded side room for big groups/parties, we all love that restaurant, my brother and i both used to work there, and they'd clean up after us. My mom was worried that we'd have to pay to 'rent' the room (we don't) and she heard from my brother that we'd have to 'pay' for a waiter (which i know my brother didn't say, my mom just misheard him) and that they won't let us bring in an outside cake (they do let you). I called Uno's, talked to the very nice head hostess and got all my/our questions answered and the party started to sound awesome! So i clear up the confusion with my mom (or so i thought), and we're back on with Uno's, i just need to reserve the room and decide how we're doing food.

Now also in this confusion is my dad. He decides to step in a few weeks ago after my mom and i are having a heated discussion where i'm *re*reminding her everything about having the party at Uno's after she *again* throws at me that she still wants to do it at the house!! The house i mentioned earlier. My dad says i can email/call him with any ideas i have and he'll talk to mom about them. The problem is, he's the worst one with this stuff! He gets info backwards or just flat out doesn't hear or understand something! So i refused. And i just refused again after getting off the phone with him a few minutes ago. Especially after he said that they were going to go by Uno's today after he got off work (and the head hostess will already be gone) and he asked how much they had to pay to rent the room. I almost lost it!! I said 'dad, do you talk to mom?', to which he replied 'yes'. I then tell him that i have told mom this *MANY* times already and then I re-re-remind him about all the info for Uno's. I said that i'm not trying to take anything away from mom helping plan this, but she's getting confused, overwhelmed and difficult and i just want to make this easier. He said 'i know...'.

And now we also need to change the date to the day before. Not like anything was reserved yet, but i wasn't even going to tell my mom till everything was reserved and the Evite went out. Cuz i know she'd flip out. For no reason.

I love my parents, i really do. But why are they making things so difficult? A few weeks ago i was to the point where i'd raise my voice to my mom any time we talked about this. But now i'm actually laughing. My grandma (my mom's mom) didn't set the best example about being relaxed when it comes to stuff like this. She'll come up with the worst case scenarios and fully believe that they will happen. And my mom is starting to do that too.

I just want my sister to have a nice party and eat pizza and open presents!!
