We singled out a few from a thorough article, 30 Ways to Baby Proof Your Home on She Knows. While they're all logical, they might not be the first things you think of when you get ready to baby proof.
• Never leave water standing in the bath, the sink or even a bucket. Babies can drown in very little water.
• Keep medication, vitamins and cosmetics away from your baby’s reach. Although we thought it common sense to keep any medication up high in our pantry, we used to always keep our prenatal vitamins out on the table, and sometimes our baby would even play with the box. One day we noticed a warning signing saying that accidental iron overdose is a leading cause of poisoning deaths in children. We moved it up in the pantry with the rest of our medications.
• Adjust your water heater temperature to 120 degrees F to prevent scalding. In some apartments you may not be able to do this. You may want to double check with the building management.
• Make sure there's no way a baby can lock themselves in any room in the house. It would be a truly scary thing to be on the other side of that locked door.
• Check the floor for small objects that a baby could swallow: pins, nails, buttons and coins. This is pretty obvious for the most part, but sometimes you forget and a coin or two drops out of your husband's pant pocket, or you drop an earring and get distracted before you can pick it up. It's amazing how babies can pick out the smallest things on the floor.
