Question: what is the average height and weight of a 6 month old baby?
Answer: 6-Month-Old Baby Weight & Length How much should a 6-month-old weigh? Average weight of a 6-month-old is 16.1 pounds for girls and 17.5 pounds for boys. Average length (height!) is 25.9 inches for girls and 26.6 inches for girls. Average or “normal” weight for a 6-month-old baby doesn't tell the whole story though.
