Hey there, i have the same problem with my daughter, when she gets bitten, they swell up to like bigger than a 50cent piece, and look really inflamed and sore. i took her to the doctor and he said use an antihistime (i cant spell it either lol) but you know what i'm talking bout, which i used, it worked to some extent, but am also myself looking for a natural remedie. i've just searched yahoo and this is what i found, hope it helps as i'm gonna give them a try too. good luck
Garlic
One of the quickest and easiest remedies for those terrible mossie bites is a simple clove of garlic. Cut a clove in half and rub it directly onto the bite. This will relieve the itching almost immediately and is safe to use on children and adults.
Home Made Calamine Lotion
Mix baking soda with water to make a smooth paste. Rub the paste over the mosquito bites. This will stop the itch and works just like calamine lotion. Of course if you have calamine lotion in your medicine chest use that as it really works well on mossie bites.
Salt
A little salty water is good. Make it up with a small amount of water to a teaspoon of salt. Dab it on the bite but do not dry with a towel. The water will dry but the salt residue will remain to stop the itching. A swim in the sea will give the same result if you are near a beach.
Aloe Vera
You may not have Aloe Vera plant growing in your cupboard, but you could get one in a pot on your window shelf or grow them in the garden. Aloe vera is a fabulous, versatile, natural remedy for all bites, sunburn and scratches. Simply break a little piece from the plant and rub it on the bite or infected area.
Other natural remedies that you can apply to bites are lemon juice, lime juice or other citrus juices that taste bitter. The inside of banana peel. Cider vinegar or white vinegar.
It is always best to put something on mosquito bites and sandfly bites for children. Children don't know the meaning behind telling them not to scratch the bites and there is always a danger of the bite becoming infected because of scratching
if these work it'll be a lifesaver, gonna give em a go, hope they work for you
