Mum shares a genius parenting hack to soothe her crying baby - and it involves a large glass of white wine.

The cute video, filmed in the family's Kansas City home on April 24, shows the small baby instantly stop crying after sucking on the outside of a cold wine glass.

Marina Rose told Newsflare: "This is my five-month-old baby girl going through a rough teething stage and finding that a cold wine glass can provide some relief.

"She is too young to hold teething toys and her mouth is too small and sensitive for ice cubes so as I’m sitting there trying to find a better resource, she started reaching for my wine glass and the rest is history.

"Now every time I have a glass of wine, she cries when she sees it until I let her suck on it."
