From the time your child starts picking things up with her fingers until the age of 4 or 5, you’ll need to be vigilant about choking hazards.
Children under 4 are the most likely to choke on something. This is partly because they tend to explore their world by putting things in their mouth.
It’s also because they’re still learning how to chew and swallow food. Babies as young as 6 or 7 months can bite off a piece of food with their new front teeth. But they won’t be able to chew it well until all their molars come in and they’ve had lots of practice with them, usually by the time they turn 4. Unchewed bits of food can block the airway or be inhaled into the lungs. Here are some ways to prevent choking in young children.
