DD not eating much after illness

[imamearcat]

I posted the other day about my 4yo DD having a temperature. Anyway she's fine now except she's not really eating properly and it's making her grumpy. She's on the slim side anyway and has lost a KG, putting her right on the line of healthy BMI.

She is eating a bit but not the most nutritious of foods - she will have fruit, milk and then a bit of bread/weetabix or similar.

I'm not sure how to handle it, should I let her have what she feels like or try to encourage proper meals?

Forgot to say, with her temperature she was complaining of a headache and tummy pain. Says her tummy hurts now sometimes after meals.

Did she loose her sense of taste or smell?, these can come back slowly and really have an impact on appetite. I’d let her eat what she wants and keep her fluids up, she will start eating properly again.

Lose not loose

Not that she said. She didn't have a cough or anything it was just this random fever and she said her head hurt when she jumped but not all the time, and then a few days later said stomach pains but no sickness or anything.
