Snot baby. Oh Lordy.

[TheRhythmlessMan]

So. Much. Snot.

Do we just have to sit it out or is there anything I can do apart from keeping DC rested/warm, Calpol, wiping nose. And more wiping nose. And maybe some more wiping.

You can try one of these but mostly its just waiting.
If it's bunged up with snot then snufflebabe balm is also good.
