A mum has been left shocked after discovering a warning on a popular brand of fabric softener.
Leah Reilly quickly posted a snap of the bottle on Facebook to inform other parents of the potentially life-threatening risks of using Lenor's Spring Awakening fabric softener on kid's clothes, Mirror Online reports.
The back of the bottle states: "Do not use this product: On children's sleepwear or garments labelled as flame resistant as it may reduce flame resistance."

Leah said: "Never seen this before but all mums need to know DO NOT PUT THIS ON YOUR KIDS SLEEPWEAR!!! Look there's a f**king warning on the back of the bottle!!!!!"
Offering a more detailed explanation, one grateful commenter added: "It rids the flame retardant off items after so long, so in a house fire you will have half or even less than half the time to get out of the house before everything that everyone sprays Lenor on is ablaze.
"It's scary I don't know why people are even joking about this."
Lenor is a firm favourite of Instagram cleaning queen Mrs Hinch who regularly uses the fabric softener on everything from curtains to bedspreads.
P&G UK and Ireland, who own Lenor, were contacted for comment.
