Choking happens when an object gets stuck in the throat or airway. This can block the flow of air and cut off oxygen to the brain. Young children may choke if they swallow breast milk or formula too quickly or if they have too much mucus.
Any object small enough to go into your child's airway can block it. This includes small food pieces like nuts, grapes, beans, popcorn, hotdogs, or food that hasn't been chewed well. Household objects like buttons, marbles, small batteries like those used in watches, coins, latex balloons, and beads are also common choking hazards. Small toy parts can also cause your child to choke.
If your child is choking, give first aid right away. This will clear the airway so your child can breathe.
