Baby walkers can be unsafe for a number of reasons:
Rollaway hazards: Baby walkers can roll away if not used on a flat, level surface, or if the brakes are not properly engaged. This can lead to injuries from falls or collisions with furniture or other objects.
Stair hazards: Baby walkers can easily roll down stairs, leading to serious injuries or death.
Burn hazards: Some baby walkers have been recalled because of burn hazards from exposed heating elements or hot liquids.
Entrapment hazards: Babies can get their fingers or toes caught in the walker's moving parts, leading to injuries or amputations.
Developmental delays: Using a baby walker can delay a baby's natural development of crawling, walking, and balance.
To make sure that the baby walker is safe for use, parents should always follow the manufacturer's instructions for use, ensure that the walker is being used on a flat, level surface, and that the brakes are properly engaged. Parents should also supervise their babies at all times when they are in the walker, and ensure that the walker is not being used near stairs or other hazards. Additionally, it's important to make sure that the baby walker is introduced at the right age and development stage, and that it meets current safety standards.
