I understand that baby below 1 years old cannot take honey. But how about honey sweet potato that is meant to make puree or mox with porridge? Thank u

Do you mean the sweet potato is cooked with honey before being pureed? In my opinion, sweet potatoes are sweet enough without the need to add honey. I'd skip the honey for now just to be on the safe side. I read that honey, even thought it's cooked, can be quite dangerous to baby.
