Keep your child who has outgrown his forward-facing car seat in a belt-positioning booster seat until they are big enough to fit in regular seat belts. Keep in mind that, according to the AAP, this is usually not until a child has 'reached 4 feet 9 inches in height and are between 8 and 12 years of age.'.
Even greater cause for concern is that a large child of 15 months who is in the 95th percentile for weight can easily approach 30 pounds. At that age a child's body is not developed enough nor likely to be tall enough for this type of seat. A good thing is that of the 28 booster seats with the lower allowable weight limits, at least half also include a minimum age limit of three and others include height limits that are more typical of a three-year-old.
