Question: how many inches do babies grow between 1 and 2?
Answer: Your toddler may gain about 5 pounds (2.27 kg) and grow about 4 or 5 inches (10 to 12 cm). By 2 years, children have reached about half of their adult height and 90% of adult head size. Boys tend to weigh about a pound more than girls but average about the same height.
