How old does a child have to be to sit in a toddler seat?

A child typically transitions to a toddler seat, also known as a forward-facing car seat, around the age of 2, but this can vary depending on the child's weight and height. It's important that the child meets the seat's requirements and that they have outgrown their rear-facing car seat before making the switch. Always refer to the car seat manufacturer's guidelines and your local laws for specific recommendations.
