What do i do?

My baby who is 8 months got a throat infection and since then she doesn’t want to eat any food or medicines. Will only have milk from bottle and has stopped breastfeeding. She will hold the food in her mouth for ages. Her antibiotics are over and doc said she is all good. I really dont want this to be a new habit. She wasnt a great eater but would try abit, but now completely wont open her mouth or if i manage to sneak a spoon in she wont eat it. I’ve tried to make her food more pureed but nothing works. She would rather sleep with hunger than eat. Any advice would be most welcome
