11 wks old and won't eat kitten food?

Looking for suggestions.........kitten was at the vets and all is good! Then why can I not get her to eat anything??? She would only nurse from momma and she is now 11 wks old and still won't have anything to do with food! I have tried many different types of food and KMR as well as goats milk and still notta!
I have separated her from momma completely today in hopes that she will get hungry enough to eat!
Has anyone else dealt this this and how did you finally get the kitten to eat??

She will learn to eat food eventually. Have you tried Gerber chicken or turkey baby food?

How much does she weigh? Does she use the litter box? Do her siblings eat well and use the litter box?

Please let her nurse from her mom in the meantime, as she needs food in her system.
