It's frustrating isn't it!! I know it seems never-ending now, but it does get better. Kids go through a phase of getting everything that goes around when they start somewhere new - day care, kindy, school etc. It usually lasts a few months then settles right down. And the good news is that once they have gone through it at day care, they usually don't go through for it so long when they change to kindy, school etc.

If it's any consolation, this build up of immunity is really good for him.
