anyone else??

this winter it feels like every time I turn around one of my kids is sick. ill take them to the doctor, give them their medicine religiously, and then when it seens like they aren't sick anymore, BAM! another one and I bundle them uo, make them wear two jackets and both hoods over their heads and their still getting sick. I'm starting to feel like bad mom cause my kids keep getting sick! the next thing I'm gonna try is giving them their vitamins everyday 😥 anyone else in this same issue?
