Accidentally ingesting a harmful, poisonous substance is a lot easier than you may think. Medication bottles look a lot alike, so clearly mark everything and keep it all out of reach of your children. If you're on several medications, you may want to get a weekly pill box to keep it all organized. Also, make sure that your child doesn't have access to any harmful solvents or cleaners -- the area under your kitchen sink is a veritable collection of deadly liquids. Teach your kids, too, what a skull and crossbones on a container means, and keep the poison control center number handy at all times.
