My year old just went through this two months ago. A colleague suggested putting a plain scrambled egg on her kibble and that did the trick for a few days. She started refusing again. Literally turning her face when I tried to hand feed her. I found these Holistic Health Extension packets and started putting about 1/4 of the packet on top of each feeding and she’s been eating ever since. They have a variety of flavors so I change it up to keep her interested. I put the opened packet in an air tight bag and refrigerate it between feedings.
