Thanks for your regard. I have stopped to give him sweet potato today and he is fine now. I did call my doctor to ask what happen to him and he replied that maybe not the problem from 蕃薯蓉. Maybe the "killer" is the 細菌from his finger as he stuck them in mouth all the time. But anyway, he suggest me to stop giving him 蕃薯蓉 and see.
Sorry to hear Hayden was not well :cry: Perhaps your doctor is right, big chance of getting virus from the "dirty" fingers as they always suck them into mouth (actually everything!). My maid and myself always alert (wash frequently) on whatever objects he might touch plus of course his fingers. My friends (who have babies/kids) suggested me don't rush into trying many varieties of food for babies, they are still too young to adapt to it ---- they have time to enjoy later.
You can try sweet potatoe later if the doctor is right.
