Several parents at an elementary school in Vegas -- attended by the children of "Sister Wives" star Cody Brown -- are up in arms, TMZ has learned ... and it's all over reality TV cameras infiltrating their school.
Here's how it started -- sources tell TMZ, a production crew for TLC's "Sister Wives" came to the Sheila Tarr Elementary School's Valentine's Ball last Saturday to shoot the Brown family with their children.
According to sources, parents at the school were notified days before filming -- but a large group strongly objected to it, and lodged complaints with the school.
In the end, we're told the school worked out a deal with the production company behind the show -- in which producers agreed not to discuss the location of the school and blur out the faces of any children not associated with the show.
But we're told several parents were still upset -- believing the cameras represented an invasion of privacy -- and now, they want the local school district to revamp its on-campus filming policies.
TLC had no comment. A rep for the Clark County School District tells TMZ, "The district heard the concerns of the parents involved and considered them when developing [the] compromise."
The rep adds, "In the past few months, we've had the Ellen show, ABC News, Oxygen Network, and countless local broadcasts filmed at our schools. TLC and the Brown family deserved the same."
BTW -- the Valentine's Ball was a fundraiser event to raise money for the school ... and we're told the "Sister Wives" production company donated $500 to the cause.
Brown and his multi-wife "plural" family claim they're filing a lawsuit against the state of Utah tomorrow -- challenging the bigamy law that makes their lifestyle illegal.
The Brown family attorney posted a statement on his blog saying, "We are not demanding the recognition of polygamous marriage. We are only challenging the right of the state to prosecute people for their private relations and demanding equal treatment with other citizens in living their lives according to their own beliefs."
The attorney adds, "It is a challenge designed to benefit not just polygamists but all citizens who wish to live their lives according to their own values -- even if those values run counter to those of the majority in the state."
The legal argument is virtually identical to the one made by supporters of gay marriage ... which is illegal in most U.S. states ... including Utah.
So, we gotta ask ...
Sources close to the fam tell TMZ various scheduling conflicts made it impossible for the whole family to get together this year. We're told the Browns had their Father's Day last week over a giant breakfast -- which included pancakes, eggs, bacon, fruit, french toast and cereal.
As for gifts, we're told each of the wives gave Kody a "survival kit" -- some of the basics he needs to have at each house -- like cologne, Q-tips, and dental floss.
TMZ spoke with the TLC reality star -- who tells us he's taking Meri, Christine, Janelle, and Robyn to the Red Rock Casino in Las Vegas for their famous Mother's Day Brunch buffet.
Kody says he isn't really a "breakfast guy" -- but his wives are huge fans of the Rock's quiche, eggs, and waffles ... and at $23.99 a pop, it fits in the budget.
Meanwhile, the Duggar family from "19 Kids & Counting" are also having a cost-friendly Mom's Day ... hitting church in the morning ... followed by a family luncheon honoring the women.
In other Mother's Day news -- TMZ also spoke with "Cake Boss" Buddy Valastro ... who told us he's finally gonna take the day off this year and spend it with his wife Lisa ... who gave birth to their 4th kid this year.
Happy Mother's Day people.
The Brown family has been making the rounds promoting tonight's premiere on TLC (even appearing on TMZ Live), but we're told whole family has returned to Las Vegas to watch the show.
A fight over the remote would be epic.
Such is the dilemma for "Sister Wives" star Kody Brown. He tells us that in the past, he's spent Valentine's Day with other polygamist families -- since most polygamists don't usually like to be too public about the whole plural marriage thing.
This year, however, is different. Brown tells TMZ since the family is "public about the lifestyle now," he's considering taking all the "Sister Wives" out to dinner together. We recommend ordering a sampler platter.
As for gifts, Brown says he usually gets cards and chocolates for each of the wives and a small chocolate Valentine for his 10 daughters. Brown says he bought Christine a necklace, but still has to shop for the other wives.
Maybe Kay Jewelers is running a buy one, get two free promotion.
As TMZ first reported, Brown and his fam recently relocated to Las Vegas so they could explore new job opportunities. TMZ spoke with several of the new neighbors and while some sound tolerant of the Brown clan ("It's a quiet neighborhood, and as long as it stays drama free, then we're fine") others want nothing to do with them.
One neighbor told us, "I don't want my family surrounded by polygamists."
Another was upset because now her young children are asking her about polygamy -- and now she plans on moving. She told us, "I am not tolerating the polygamists or their TV show in my neighborhood."
Sources close to the polygamous posse tell TMZ ... Kody is renting three homes on the same block in a Vegas-area community -- and TMZ obtained photos of K-dog moving Meri into house #1 earlier this week.
We're told the rest of the fam will be spread out in the other two homes -- with two of Kody's 4 wives doubling up in one house.
As we first reported -- Kody moved the gang to Nevada so he and his wives can "explore new job opportunities" -- and although the details of the new careers are still unclear ... Kody seems to have a future in moving.
TMZ has learned Kody and crew moved into their new temporary rental home in Sin City late Tuesday ... but it wasn't an easy journey.
Average travel time from the Brown's home in Lehi, Utah to Vegas is roughly 6 hours ... but Kody's caravan took 30 HOURS to complete the 397 mile voyage.
We're told the gang was slowed down by "multiple car issues" -- including EIGHT blown tires!!!
As we previously reported -- Kody and the rest of his polygamist family moved to Nevada to "explore new job opportunities" ... but it's unclear what kind of career moves they're looking to make.
Sources close to the Brown's -- all 24 of 'em -- tell us Kody will be moving the gang to Nevada so he and his wives can "explore new job opportunities."
Brown -- who was at the center of the felony bigamy investigation in Utah -- shouldn't face as much scrutiny for his living situation in Nevada ... where cohabitation between a man and his unlicensed "wives" is not a crime.
Brown family attorney Jonathan Turley tells us neither Kody nor his wives have been hit with any charges stemming from the Utah investigation.
As for the move -- we're told the fam should be on the road in the next few days.
We're told the Brown family will be hitting up a costume party on Sunday -- and the four wives will be dressed up like earth (Janelle), air (Christine), fire (Meri) and water (Robyn).
As for fifteen of their sixteen kids (it's hard to keep up with them all) -- we're told they'll be disguised as two vampires, one hippie, two nerds, one goth fairy, one regular fairy, one zombie, an M&M, Cleopatra, a gangster, an angel, a mobster, a "Twilight" vampire, and one "ugly mask."
And last but not least -- we're told Kody has yet to make up his mind about an outfit ... which probably explains why he has FOUR WIVES.
