If a child swallows a 10-cent coin, it may be swallowed into the stomach due to its small size. The child is not showing any abnormalities, indicating that there is no risk of choking. Since the coin is round, the risk of causing serious harm even if it stays in the stomach is low. It is recommended to further observe the child’s condition and find the coin to confirm if the child actually swallowed it. If unsure, observe for any signs of the coin being passed and consider taking the child to the hospital for a check-up if concerned. Generally, it can be inferred if the child has actually swallowed it.
