Mum’s genius hack ‘cures’ dangerous dehydration fast – and costs as little as £1.40

 shared a mum's genius hack to cure dangerous dehydration fast - and it's pretty much guaranteed your kid will enjoy it, as it involves jelly.

The team behind the Instagram page dedicated to baby and child first aid asked their followers who are medical professionals to give them hot weather tips.

One replied that if your kid doesn't like re-hydration drinks like Hydralyte, you should add it to jelly for jiggly hydration boost.

All you'll need are some electrolyte re-hydration tablets and a packet of powdered gelatin.

Make sure the gelatine is unflavoured, Tiny Hearts Education noted in the caption to their .

"Oral re-hydration solutions are specifically formulated to contain balanced essential electrolytes and shouldn't be mixed with cordial, fruit juice, soft or sports drinks, as stated on the packaging," the medics explained.

"Make sure you use unflavoured gelatine for making these hydration jellies as normal jelly may contain high sugar levels, which can interfere with the re-hydration process."

You can nab a pack of three Dr. Oetker Gelatine Sachets for as little as £1.40 at Tesco or £1.30 at Asda.

Once you've got your ingredients together, mix the unflavoured gelatine with boiled water and make up the oral hydration solution in another glass, following the instructions.

Next, add the re-hydration solution to the gelatine mixture and then pour into cups or your desired vessels.

Pop those in the fridge and voila! You have hydration jelly, ready for your tot to enjoy in a moment of need.
