Hilary Barry has reminded parents of young children that a little dirt never hurt anyone - quite the opposite, in fact.
Speaking on "The 3pm pick up with Hilary Barry" show on The Hits this week, Barry quoted a new study from the Journal of Allergy and Clinical immunology, which found that sterilising dummies with antiseptic solution has been linked to children developing food allergies.
"You know the three-second rule for food? Or is it five seconds?" Barry asked co-host Estelle Clifford.
"I've got news for all the parents. You should be doing the same for your dummies. When dummy drops on the ground, instigate the five-second rule," she added.
