All my little one wanted when he was poorly was melty sticks and sometimes toast x
Our little boy will only eat ready break or yogurt when he is ill
I was told by the doctors that as long as baby drink to worry too much about food but if you really want baby to eat try purée fruit and veg as they are liquid enough to not hurt baby’s throat if it’s sore
This is a typical Indian home food for anyone who is sick - called Khichadi (or kedgeree) - it is basically mung beans dal cooked with rice in lots of water. Tastes really nice with butter and yogurt and is very easy to digest. Really good for a bad tummy at any age
Honestly I'd not worry greatly about food while poorly and just push fluids and offer food when you eat or they show their signs and stick to bland/plain food then too xx
