Lightbrite,
When are your kids old enough for you to un-babyproof your home?
Depends on the family. By age 3, many toddlers can open baby gates themselves and can pull chairs over to access items on shelves, and babyproofing gives way to chinuch. But then there may be younger siblings, and eventually iy”H grandchildren.
BTW, sharp edges can be a bane for adults too, not just children!
