no that is healthy
healthy babies come in many shapes and sizes. At six months, anywhere between 14 and 21 pounds is considered a healthy weight for boys. (Although, five percent of healthy boys weigh less than 14 pounds and five percent of healthy boys weight more than 21 pounds). Healthy boys who are 28 inches long, whatever their age, usually weigh 16 to 22 pounds. So 17 or 18 pounds is a great weight for an active boy to be!
Definitely. He is right in the middle of the "Healthy" range mostly because he is tall and his weight is well distributed.
no, that's extremely underweight... you should weight at least 120 pounds
