Advice on future grandparents-who's in the wrong?

Hi all! This will be long! Sorry!

So my husband and I are 22 weeks with our little girl. She is the first grand daughter on his side and the first grand child on mine. He has three nephews so when we found out she was a girl, it was a huge deal!

My in laws like to go over and beyond, especially when they get excited, and this past weekend they went and bought a SHIT ton of 0-6 month clothes. Like there's so many, she doesn't need anymore of those sizes. I've had to get rid of some just to make room in her closet.

My mother in law posted pics of all the clothes she got my daughter on Facebook and my family saw it.

This is where things get messy.

I thought nothing of it, other than being a tad frustrated cause I still had some things that I wanted to get her in those sizes and now there's no point.

I spent an evening with my parents, and my mom brought it up. She was obviously pissed, and so was my dad. My grandmothers are also upset about it. Which leads me to think that my parents aren't over reacting about it because my grandmothers will usually tell them they're being stupid. But they're upset too. My mom flew off the grid and just went off about it. I obviously still need 6-12 and up clothes, but everyone loves to buy smaller sizes I guess. I told my mom that I still needed bigger sized clothes. But she didn't seem to care.

She also said that if we didn't say something to them (my in laws) that they weren't going around them. And I said what about birthdays. And she flat out told me no. That they'll have a party for her, just my side, and my husbands side can do one for her. But they are now refusing to even try to look past it and get along.

I had to bring this up to my husband since my parents were so ticked about it. He can't hardly stand them anyways because they usually always have some kind of drama going on. He's mad at them because he thinks his mom and dad were trying to help us be as prepared as we could possibly be. It was their way of being thoughtful! And it was a large percentage of our baby shower gift from them.

I'm torn between the two. I can see how my parents feel, and how it may have looked that my in laws posted a pic of everything on Facebook. BUT, I also see where my in laws were coming from, and it was from love, and support, and pure excitement!

So from an outsiders point of view, who's in the wrong, and what should I do about it? I'm expected to fix it, get rid of the stuff, downgrade, or just let it be and have a torn family.
