After the picnic, promptly put leftovers back in the cooler. If the cooler no longer contains ice, then don't try to save perishable leftovers. Preventing Choking When picnicking or whenever you're feeding children, parents and care givers must always be alert to the danger of choking. A choking child is a silent child. Each year as many children die from choking on food as from eating food that has been contaminated with bacteria or toxins.
Risky foods tend to be small, round, firm and slippery.
The child under 4 usually finds such foods difficult to hold in place and chew. Round foods cause trouble because they fit so well into a child's airway, which is small and susceptible to blockage. Hot dogs, a popular picnic item, head the list of foods that children choke on most often. Slicing a hot dog lengthwise and then cutting pieces at an angle ensures odd-shaped pieces that are less likely to cause a child to choke. Environment also plays a part in choking.
