Answer:
To at least 1 year Old
Step-by-step explanation:
Due to the report from a study that suggested that children who are moved from safety seats to regular seat belts are much more likely to sustain severe head injury when involved in a crash, Buckle Up America had to form 4 steps for parents and caregivers to follow in order to ensure maximum child safety when in a moving car. The first step is to ensure the "use of rear-facing infant seat in the back seat from birth" till the child is at least 1 year old and weighs at least 20 pounds.
