My toddler flu and cough been like 2 to 3 weeks still not cure. Is it ok? Cuz he's in childcare so is normal? Any soup that I can make for him to feel better? Drink medicine drink till gong gong...legs and hands cold cold

For his cough, you can consider bringing him to TCM. It helps to 'tune' his immune system and treats those long coughs too. Secondly, any soup is good. Importantly maintain a healthy diet. And yes its very normal for children to fall sick often while being in childcare. You can also offer multi-vitamins to strengthen their immunity system
