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. Keep bathroom doors closed. The bathroom is one of the most dangerous rooms in the house. Ceramic floors and fixtures are one of the hardest surfaces a child can hit his head on. Toilets beg to be climbed making falls even riskier.
Curious babies have on occasion drowned in toilets.
All toxic materials should be kept out of reach and preferably in a locked cabinet. If you store cleaning materials under a sink be sure that the cabinet has a child proof safety latch. Keep all toxic materials in the original container. The label has important information that can help you in the event of an accidental ingestion. Without a label you might not even remember what is in a container.
