Fireplaces, wood-burning stoves, and radiators. If you have a fireplace, wood-burning stove, or steam radiators, teach your toddler to respect the warnings "Hot!" and "Don't touch!" Never leave a child in the room alone with a heat source, even if she seems safely enclosed in a play yard or bouncy seat. Consider a fireproof safety railing around the woodstove or fireplace, and always use a fireplace screen. If your fireplace has a glass enclosure, keep your child from touching it. Put fireproof padding around sharp edges on raised hearths.

Glass doors and objects. Put large stickers on sliding glass doors to keep your child from crawling, walking, or running into them. Remove vases and other knickknacks your child could break, fall on, or swallow.

Houseplants. Give away poisonous houseplants (dumbcane, dieffenbacia, philodendrons, calla lilies, mistletoe, and hyacinths, to name a few), or ask friends to take care of them until your child is older. Keep all remaining plants well trimmed, so a child can't reach them.

TVs, VCRs, DVD players. Childhood injuries and deaths from falling television sets are a growing problem, according to Consumer Product Safety Commission statistics. (See our report on TV tipover dangers.) The TV, VCR, and DVD player should be placed out of your child's reach. Secure them on a wall-mounted stand or on a shelf fastened to the wall.
