My 19 months old LO has yellow discharge on her eyes, especially when she wakes up from her sleep. Sometimes, it gets so sticky that she finds it hard to open her eyes. Anyone has any experience on that?

My lo's corner of de eye got some redness.. Flush with bm.. Got some improvement but still worried so brought to see doc.. Given eye drop n some vicous liquid for eyes too.. After 5days, no more redness or yellow discharge..
