Can't really protect your kids from a cold.
Did you know that a cold is most contagious 24 hours prior to someone actually having symptoms??
Which literally means you can't protect your child from it. Just keep them healthy and strong so it will limit how long it lasts or the severity.
This information both freaked me out and made me relax more. Knowing that they're just going to get sick and I couldn't Akways stop it? Let me relax a bit.
