I guess my kids are just abnormally healthy! LOL I've been taking them to OEYCs since they were babies and they are constantly exposed to many viruses throughout the year but I can usually bank on one good fever and a cold.... for the YEAR. It doesn't seem normal to me that kids are sick every 2 weeks. They constantly asked for unhealthy foods so I guess I'm not surprised about their immune system but even so... my nephew eats terribly and even he's not sick every 2 weeks!
