Look for sharp edges or corners on tables. Consider padding corners on tables in rooms where toddlers play regularly or removing those tables to another room. Look for small objects on the floor such as older children's toys. Babies love to explore the world with their mouths. They put everything in their mouths.
Small objects are a choking hazard.
Check for poisons that may be in reach of your baby. That includes plants which babies may chew on. Make note of any unprotected heating vents or radiators which are in reach of your baby. Touching these could result in a burn. Once you have noted where these risks are you can make a point of keeping your baby away from them or block access to them.
