A determiner is a word that modifies a noun or a noun phrase. Thatâs also the definition of adjective, but although both parts of speech modify nouns, determiners are distinct from adjectives in several respects, most obviously in that the latter express attributes, whereas determiners express relationship. determiner is a word that modifies a noun or a noun phrase.

Stephanie Tombrello. child passenger safety specialist. You can safely switch your child to a booster seat if she's at least 4 years old and she weighs 40 pounds or more or has grown too tall for her car seat (when her shoulders are higher than the top set of harness-strap slots in the car seat's back).n a crash, belt-positioning seats are far safer. (If you have only lap belts in the rear of your car, select a booster seat with an extra energy absorber belt.) Backless booster seats tend to provide a better fit than the high-back kind, and are more portable when you're switching them from car to car.
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.
