To check your childproofing efforts, get down on your hands and knees in every room of your home to see things from a child's perspective. Be aware of your child's surroundings and what might be potentially dangerous.
Completely childproofing your home can be difficult. If you can't childproof the entire house, you can shut the doors (and install doorknob covers) to any room a child shouldn't enter to prevent wandering into places that haven't been properly childproofed. For sliding doors, doorknob covers and childproof locks are also great for keeping little ones from leaving your home. Of course, how much or how little you childproof your home is up to you. Supervision is the very best way to help prevent kids from getting injured. However, even the most vigilant parent can't keep a child 100% safe at all times.
Whether you have a baby, toddler, or school-age child, your home should be a haven where your little one can explore safely. After all, touching, holding, climbing, and exploring are the activities that develop your child's body and mind.
