I appreciate that this is probably all relative, but as a new parent I'm interested to hear your experiences. One of my friends has a 2yo and a 7yo and they seem to have constant bugs all the time with hardly a break in between. But another friend with similar aged kids never seems to get anything. I'm pretty sure Friend 2 just doesn't broadcast it, and they get their share of bugs like every other family. But these seem to be two opposite extremes. What's normal? What am I in for as my LO gets older?
