From the Research

If your child has swallowed Hypernerf blaster balls and is not showing any symptoms, you should still contact Poison Control (1-800-222-1222) or your pediatrician for guidance. While most small plastic toys pass through the digestive system without causing harm, there are potential risks including choking, intestinal blockage, or chemical exposure from materials in the foam 1. The danger depends on the size of the ball, how many were swallowed, and your child's age and size. Do not induce vomiting unless specifically instructed by medical professionals. Monitor for symptoms like abdominal pain, vomiting, difficulty passing stool, or changes in bowel movements.

In most cases where a child remains asymptomatic after swallowing a small foam ball, medical professionals typically recommend monitoring the stool to confirm the object has passed, which usually occurs within 1-3 days 2, 3, 4. The digestive system is designed to move foreign objects through, but medical guidance is essential to ensure safety. It is also important to note that intestinal obstruction can be a serious condition that requires prompt medical attention, and any delay in surgical intervention can lead to higher mortality 3.

Some key points to consider include:

  • The size and number of balls swallowed
  • The child's age and size
  • Monitoring for symptoms like abdominal pain, vomiting, and changes in bowel movements
  • The importance of medical guidance to ensure safety
  • The potential risks of intestinal blockage, choking, and chemical exposure from materials in the foam 1.

It is always best to err on the side of caution when it comes to the health and safety of children, and seeking medical guidance is the best course of action if your child has swallowed Hypernerf blaster balls, even if they are not showing any symptoms.
