Check the floor often for small objects such as coins or paper clips, on which a baby might choke. Especially during your child's crawling stage, you'll probably need to vacuum more often than usual. It will be a long time before your baby is old enough to learn which objects are OK to play with and which things are off-limits. You'll save time and energy by putting things up until she's older. Cleaning products and medications are life-threatening and should be put in high places and locked up.
Many plants are toxic when eaten, and little kids do love to explore things with their mouths.
Most parents find it easiest to keep all plants well out of the reach of their child's curious hands. If you have open stairways, they should be blocked with an approved safety gate. Be careful about buying or borrowing old gates, which may not meet current standards. Finally, think about the quality of the air your child breathes. If there are smokers in your household or among your friends and family, remember that secondhand smoke poses a significant health threat to children.
