It will get better.
And the good news is that by spring/summer those runny noses will finally go away and you will forget all about them until approx Sept.

My first year I got sick and sore throats a lot. This year the kids around me are sick with various issues and my kids are sometimes sick but I seem to be skirting by.

I try to drink some OJ if I notice any hint of sniffles on myself and make sure I try to get rest at night and so far (knock on wood) so good this winter.

I think as long as you vigorously wash hands and your hands then you will get pretty good by next fall :-)
