Leah Messer Rips Miranda Simms For Refusing To Help Daughter With Muscular Dystrophy

Is there a new monster mom on Teen Mom 2? Despite Leah Messer facing criticism for her parenting skills all season long, she slammed her ex-husband Corey Simms' wife Miranda for refusing to help her stepdaughter Ali, who suffers from muscular dystrophy, carry her heavy backpack.

"Miranda always gets mad at me cause my backpack is too heavy," the 6-year-old heartbreakingly said in a recording sent to Leah by her cousin. "I give her my backpack when it's too heavy… she says, 'Ali, I have to hold the baby.'"

Ali even revealed how Corey and Miranda's daughter Remi "always gets to get attention."

"I can't watch it without getting angry or wanting to cry… I don't know what to do," Leah told her sister Victoria, who responded, "Carry the f**king backpack too!"

Victoria continued, "There's nothing wrong with you going down there and saying, 'I'm tired of my kids hurting.' Ali has a condition, she can't help it that she can't carry the damn backpack. So the lazy b***h needs to pick the backpack up and carry it for her period. There is no reason that kid should feel that way."

"It is Corey's fault just as much as it is Miranda's," Leah said. "I would have never, ever thought he would allow this to ever happen to our kids."

Throughout the season, Leah has been the one to face backlash for her parenting skills.

On last week's episode, fans blasted her for feeding her 3-year-old daughter Adalynn with ex-husband Jeremy Calvert icing and sweet n' low packets.

On the season premiere, Messer refused to feed her daughters breakfast before school.

As for Ali, her condition has gotten worse, as the parents revealed she has been falling more and has been having trouble eating.
