How long have your LOs’ colds lasted?

We’re on day 9 and it doesn’t seem to be improving... congested, runny nose, fussy, and only stays up for maybe an hour before needing to go back to sleep.

He’s gotten 4 colds now and each seems to last well over a week. It’s like he’ll be healthy for a few days and is then sick again for 2 weeks... it’s miserable for him and us.
