How do you keep your kids protected against the rainy season especially when they go to school?

Yes, vitamin C or multivitamins for the kids. Plus of course, don't forget the raincoats, kiddie boots and umbrella. Also don't forget to remind them not to play in the rain when you're not watching. Some kids tend to play in the rain when parents aren't watching. Once they get home from school, always check if they have been soaked in water and change immediately.
