Have a toddler whose head is rapidly approaching the height of your tables and counters? You can spend $20-30 buying corner guards and bumpers at your local babyplex, or simply get some foam pipe insulation at the hardware store for only a few bucks. (Amazon also sells it, for $1.49 per six-foot length.) These foam tubes are pre-slit to fit easily over a table or counter edge. We’ve been using them at our house for a while now, and our son remains concussion-free.
