When it comes to food allergies, it surely goes without saying that doctors know best.
One poor mother has been left horrified, after her mother-in-law insisted her son would 'grow out of' his severe peanut allergy, if she just fed him peanuts every day.
Explaining her situation on Reddit, the mum-of-one said her mother-in-law always 'blamed her' for six-year-old's allergy, despite many trips to the doctors and attempts at introducing the forbidden food.
The allergy is so severe, doctors were clear that the child should not consume peanuts.
According to the mum, things really came to a head in a recent incident, sparking significant distress.
"A couple weeks ago, my MIL was babysitting my son and daughter when my husband gets a frantic call from her that my son was having trouble breathing and that she's taking him to urgent care," the mum wrote. "I ask her in a panic what happened and she tells me he had eaten something bad..."
The boys parents immediately rushed to the hospital, and when they arrive, grandma is in the process of making a shocking confession to the doctor - she fed the young boy peanuts.
"I was so mad my blood was boiling!", the enraged mum said. "She gave my sweet son a big spoonful of peanut butter after I told her he can't have peanuts..."
While the little boy is now fine and MIL 'did apologise', the woman is understandably concerned about leaving her alone with the kids anymore.
"She started crying saying that we don't trust her anymore and she doesn't feel appreciated," the mum wrote, adding that she's only allowing supervised visits.
According to the mum, her six-year-year later revealed that he 'told grandma he couldn't eat peanut butter but she made him'.
"I do think she loves my kids but to think she put my kid in danger like that makes my inner mama bear never want her to be alone with the kids again!," she concluded.
"My husband said he'll leave it up to me, but I honestly don't know if I'll ever be able to leave my kids with her without worrying. Am I being too harsh?"
Redditers immediately rushed to the mum's defence, praising her response and reassuring her she hadn't over-reacted.
"No, no, no!!! A thousand times no! Do not EVER allow this woman near your children unsupervised again!." said one. "What if she had ignored his breathing difficult saying he was just being dramatic? Her incredible disregard for your sons allergy could very well have results in his death - and for what?"
"Of course you don't trust her. And she should know it. It could have ended badly. I wouldn't let her babysit unsupervised until the kids are old enough to not get forced into eating something they're allergic to. So probably 25," another agreed.
"Never, you lost that privilege when you tried kill him with your willful ignorance. Be thankful you're allowed to see them an all," chimed in another.
"As a parent of a child with a severe peanut allergy, that would be a hard NO. You would actually be within your rights to go to the police and have her charged with endangering your child."
