Give her some fruit salad. It's beautiful. I'm sure she will eat it.
You cut bananas, apples, kiwis, pears, watermelons, etc. Cut it into pieces or slices, and then pour yogurt on it (that is, frozen yogurt sold in the supermarket freezer)
When she has an appetite, you can take out the frozen mung bean porridge to eat.
If you are afraid of insufficient nutrition, you can add some cold dishes. You can cook whatever cold dishes she likes. If you are not good at cooking, you can buy some.
When his appetite is good and not hot, he will eat automatically.
