Fussy Eater 14mo

My baby has always been a good eater, she has had a couple foods she’s disliked but almost never refused to eat until this week. She was sick and teething and suddenly refused to eat for 5 days straight. She’s actually lost weight and looks noticeably thinner. We’ve taken her to the dr twice and only been told it’s good she’s drinking fluids still and she’ll start eating again soon. I am wondering if it’s more of a behavioral issue now that her sickness is getting better.

How do you get your babies to eat?!?
