There are lots of Vancouver based companies in the child safety category who can not only help you identify the dangerous stuff, but also have a variety of solutions to help keep your child safe. There are Vancouver baby and child proofing places and those who can install car seats safely but child safety does not stop when your child gets past the toddler stage.
Safety also covers such things as bike/rollerblade safety, fire safety, street proofing and internet safe surfing.
Practice. Role play the situations and work on their responses.
Finally, keep emergency numbers in your home at your child's eye level. Ensure that the Vancouver Poison Control Centre number and your home address are both posted near the phone. If at all possible, invest the time in a half or full day emergency first aid course. They are listed in the Health and Wellness section and may save a life one day!
