These types of balloons might be harmless and fun, but they can choke kids to death if they blow up or chew on them. What’s even riskier is that when swallowed, they take the shape of the child’s throat, blocking their breathing.
Solution: Use only Mylar balloons. Don’t leave your kids alone with latex balloons and teach them not to chew on them. Dispose of the pieces once the balloons pop.
