There are some foods that are appropriate for adults that could be harmful for young children. According to the American Academy of Pediatrics, food accounts for over 50% of choking episodes. 

The American Academy of Pediatrics recommends that the following foods not be given to children younger than age 4:

Hot dogs

Nuts and seeds

Chunks of meat or cheese

Whole grapes

Hard or sticky candy

Popcorn

Chunks of peanut butter

Chunks of raw vegetables

Chewing gum.

When preparing food for young children, be sure it is cut into very small pieces, less than 1/2 an inch. If serving hot dogs be sure to slice them lengthwise first to prevent the risk of choking. Nannies should always encourage children to sit when eating, to chew foods well and to not lie down with food in their mouths. Nannies should always supervise children when they are eating.
