Question: are booster seats safe for 5 year olds?
Answer: If your 5-year-old reaches the weight or height limit on his forward-facing car seat, transition him to a belt-positioning booster seat. ... Your child should stay in a booster seat until the seat belt fits properly without it. For most kids, that happens around a height of 4 feet, 9 inches or around age 8 to 12.
