Are there any natural mosquito repellents that one can make at home for the kids? I don't like the patches.

I tried the "Lavender Vanilla Mosquito Repellent" which is made from: lavender oil (15-20 drops), vanilla extract (4-5 tbsp), lemon juice (30 ml) and distilled water (500 ml). Mix them thoroughly and then use as a spray on your skin or clothing.
