When to Make the Change from Car Seat to Booster Seat

A question that every parent has to face sooner or later… when is my child old enough or big enough to move from a car seat with a 5-point harness to a booster seat?

Unfortunately, there is no set age or weight. Fortunately there are some factors that can help you make the right call to ensure the safety of your child(ren).


According to “Car Seats for the Littles” (csftl.org), more important than age or weight is the child’s maturity level. According to the site:

“Moving a child to a booster seat gives them freedom that they’ve never had before: freedom to lean sideways, slouch, bother their sister, pick up a toy off the floor, and so on and so forth. If a child is wiggling out of position at the time of a crash, that leaves them vulnerable to serious injury.

That means the decision to move from harness to booster is rooted in the child’s maturity. The ability to sit correctly for the entire ride, 100% of the time, happens somewhere past age 5 for most kids, and not until 6 or 7 for a many others.”
