The American Academy of Pediatrics recommends that children younger than 4 years old should not be fed any round, firm foods unless they are cut into small, nonround pieces. Young children may not chew food correctly before swallowing. This increases the risk of swallowing the food whole and choking. Food to avoid or cut into small pieces for children younger than age 4 include the following:

• Hot dogs

• Nuts

• Meat chunks

• Grapes

• Hard candy

• Popcorn

• Chunks of peanut butter

• Raisins

• Raw carrots

In addition, always supervise your young children when they are eating. Sometimes, choking can happen when an older child feeds a younger sibling unsafe food. Young children should also sit while eating, and never walk, play, or run with food in their mouths.

Nonfood items that are small, round, or conforming can be a choking hazard to young children. Examples include:

• Coins

• Small balls

• Balloons (inflated and deflated)

• Marbles

• Small game parts

• Small toy parts

• Safety pins

• Jewelry

• Buttons

• Pen caps

• Small button-like batteries (for example, watch batteries)

• Small refrigerator magnets
• Pieces of pet food
• Pills

These hazards include the following: 

• Infants can suffocate in soft bedding, or when a person rolls over onto them in an adult bed.

• Plastic bags or wrapping that cover the nose and mouth of infants are another common cause of suffocation.

• Children can also suffocate or otherwise injure themselves when they become trapped in toy chests and household appliances, such as dryers.

• Children can strangle themselves with products that wrap around the neck, such as clothing, scarves, drawstrings, ribbons, necklaces, pacifier strings, and window blind and drapery cords. Medical devices, such as feeding tubes or oxygen tubing, can also be a strangulation hazard.

• Small passages through which a child can fit their body, but not the head, can strangle a child. This includes spaces in bunk beds, cribs, multifloor laundry chutes in older homes, playground equipment, baby strollers, carriages, and highchairs.
