I am with Stella's. I would keep nursing morning and evening and she will eat at some point at daycare. Is she already at daycare? Or are you still on leave? At home she knows she can have the breast instead but when mama is bit around, she will eat eventually.
I get it 11d. You know she'll be ok, but there is some sort of deep ingrained instinctual thing where we all go "zomg! I need to nourish my brood!". There is a drive there.
Eating issues are the absolute worst. I know it doesn't stop the fear to hear that it will be ok. She's still breastfeeding often? If you've worked with a lactation consultant have you discussed this with her? Has your pediatrician generally been supportive of breastfeeding? If you're not comfortable cutting out the breastfeeding you can rethink that. NOT JUDGING. Just don't want you to be pushed in a direction you are not comfortable with. It's so hard - I hope everything works out soon.
