Apologies if this is a really stoopid question.
I have always had cotton buds in my house which I use for cleaning my ears out correcting make up mistakes. But it has occured to me now that I am expecting DC1 that they are always in the baby section of the supermarket, but what do you use them for on a baby? 
You're not supposed to use them for cleaning ears out and I don't think I would even want to attempt that on a wriggling baby as I can see that resulting in a trip to A&E but I cannot for the life of me think what else you use them for.
Any suggestions?
