I hope it's fixed for her!

A friend of mine had this with her little boy. For the first 8 months his eye was constantly gunky, and it continued until 12 months. At that age they decided to have it cleared. Took ten minutes and it's never come back again

If you're going to need a GA for it, as a parent I don't recommend it because it's horrible to see, but if it doesn't clear up it's quick and painless.
