If you're the mother of a baby with allergies, you'll know all-too-well that managing them can be a challenging and stressful affair - and very much a team effort.
Spare a thought then for one "livid" breastfeeding mum whose "control freak" mother-in-law ignored her bub's cow's milk allergy, despite being aware of it.
In a post to Mumsnet, the author shared that she is on a strict "no dairy" diet, due to her baby's condition. After being invited to dinner, the mum said she'd informed her mother-in-law three times about her dietary requirements.
"I even messaged this morning to say even no seasoning that contains dairy," she writes. "Fast forward to me tucking into chicken breast and plain potatoes her partner lets slip about the ready basted chicken in the bag being so handy ...basted in ... butter."
Unfazed, the author's MIL simply said she'd peeled the skin off once it was cooked.
By this stage, however, the mum said she'd already eaten " a decent chunk of it" and there was "no turning back".
"I'm so f***ing angry," she said. "I was so shocked I didn't say a single word but I wish I had."
The frustrated mum explained that she was ready to call her mother-in-law and say they're not coming again for dinner "until she's willing to respect something as vital as an allergen."
"[The] same woman point-blank refused to see [the baby] had a cow's milk allergy as the doctors are always coming up with new silly things," she wrote. "Yeah cause the nearly eight hours of crying a day and sore nappies were mine and the doctor's imagination."
Adding that she was up for a literal shit few days, the mum said her husband had offered to call his mum for her.
"I think he's just scared I'm going to let loose about it," she said. "So maybe I'll let him do the talking in case I lose my head."
Responses to the mum's story were polarising.
"Wow just wow. I wouldn't let that woman near me or my dc (dear children) ever again," one commenter wrote.
Others, however, felt she was overreacting.
"She said she took the skin off the potatoes which demonstrates ignorance more than malice," one woman wrote. "Try to educate her rather than berate her."
According to ASCIA, the peak professional body of clinical immunology/allergy specialists in Australia and New Zealand, around two per cent of infants have a cow's milk allergy. Allergic reactions range from mild to severe. While most children outgrow cow's milk allergy by the age of three to five years, in some people cow's milk allergy may not be outgrown.
ASCIA also notes that breastfeeding mothers may sometimes need to remove cow's milk protein from their diet. "The need to avoid cow's milk protein by a breastfeeding mother should be confirmed by your child's medical specialist," they write.
