Final answer:
Children who weigh more than 20lbs should face in the direction implied by option 1) >20, indicating they are over 20 pounds. Expected weight gain in toddlers would lead to an average weight of around 25 pounds by age three if they weighed 20 pounds at one year old. (option 1)
Step-by-step explanation:
The question seems to be missing some context, but based on the information provided, it appears to be suggesting an answer regarding weight suggestions for children's safety in car seats. However, since the specific context is not completely clear, and we do not want to assume it is specifically about car seats, it is safest to state that children who weigh more than 20lbs should be designated as option 1) >20. This indicates that these children are over 20 pounds.
Regarding growth patterns, on average, a newborn's weight doubles in six months and triples by one year. By the age of two, the weight is expected to have quadrupled, making it reasonable for a child to weigh between 20 and 40 pounds by then.
Toddlers ordinarily continue to gain weight, and by the age of three, if a toddler weighed 20 pounds at one year, they would likely weigh more than 20 pounds given normal growth expectations, possibly around the 25-pound mark, which corresponds to option B. 25 pounds based on standard growth patterns.
Hence, the answer is option 1
