I didn't even know you could get a flu vaccination with a nose spray, let alone that it's 55% more effective than a flu shot on children. Olivia's first year was miserable all around, with everyone constantly sick. Two plus years later, and we've been quite fortunate at being relatively bug-free. Well, I guess I should say bug-resistant, because it's normally our friends who end up with the colds and flu. Maybe the immune system is like a muscle... use it, it gets stronger.

Perhaps it's nature's way of ensuring that, once a child gets past their first year, the germ vector in Keds won't kill their parents.
