1. Teach children not to talk with their mouths full, as this increases the chances of choking.
2. Be a stickler for this rule: children are not allowed to play or run around while snacking or eating. Many choking accidents occur because children are playing or running around with food or candy in their mouth. Have them sit down when they eat.
3. Teach children about the dangers of soft candy. Better yet, demonstrate it to them: take some play-dough and rip it up into small pieces. Pretend the pieces are skittles. Then take a piece and ask them, "do you think this could block your throat and keep you from breathing? Then one by one, add the pieces and clump them together while asking the same question. Explain that soft candies are just like this play-dough, so they should never try to eat too much at one time and always chew very carefully. If you draw a face on your hand and get silly about it, this makes a good group time demonstration that teachers can do with younger kids.
