Bolt whatever you can to the wall with brackets, and push items like televisions back from the edge of furniture or move them out of reach. Babies start pulling up on things shortly after they start crawling. You may think that a particular piece of furniture is just too heavy for a little one to move but this pulling up action performed on a top heavy chest of drawers make it quite easy for a baby to rock the furniture just enough to start a chain reaction. A good habit to get into is to always close drawers completely then your baby will have less of an opportunity to get a good grip on these heavy pieces of furniture. Doorway safety gates are a good way to limit your baby's access to different parts of the house.
Most parents consider safety gates essential safety items.
Safety gates allow you to contain your little one within a certain room and to block access to dangerous stairways and rooms that are off limits such as a bathroom. Make sure to choose a gate that your baby cannot dislodge but that you can easily open and close. To gate off a stairway, install a gate that screws to the wall rather than one that just stays put by using pressure for the top of the stairs. Install smoke detectors in the hallways near every bedroom and one near the kitchen. Check them monthly to be sure they are working properly and change the batteries every six months.
