should a 4 month old be 18lbs?

mine was almost 15 at her 4 month Dr's visit

mine was 13 pounds at 4 months

@melinag_, how much did she weigh when she born

one of my boys was 17lbs 9oz and his brother was 15lbs at their 4 month appointment

@paris876, she was 8 lbs 1 oz

My son weighs 13lbs now at 2 months. So if he keeps up he will prolly be round that at 4 months.

all babies are different

All babies are different. My daughter is 16 or 17 pounds and she is 5 months old

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

my 2 month old is 13lb 7 oz and 24 in long

mine is 19 pounds 4 ounces
