My son was 17 pounds 13 ounces at his 4 month check up. He was 7 pounds 15.5 ounces at birth. So I would say yes
All babies are different. My daughter is 16 or 17 pounds and she is 5 months old
My son weighs 13lbs now at 2 months. So if he keeps up he will prolly be round that at 4 months.
one of my boys was 17lbs 9oz and his brother was 15lbs at their 4 month appointment
mine is 19 pounds 4 ounces
