Dr. Megan Miller says there is a wide range of normal weight for a 40 week infant.
She says the average weight can be somewhere between 7.5-8 pounds, and an underweight infant weighs less than six pounds.
While some pregnancy apps give you an estimate of what your baby weighs at this stage in pregnancy, Dr. Miller says that becomes less accurate the farther along you are.
“Generally it’s pretty accurate, especially as babies are smaller because early in gestation, babies all grow around the same rate, when you get later in pregnancy, you can’t tell because some babies come out and they’re ten pounds and some come out and they’re eight pounds so later in gestation or later in pregancy, probably not as accurate,” says Dr. Megan Miller, M.D. OB/GYN at Sanford Health.
She says your baby can be considered overweight as well.
Dr. Miller says that’s when your 40 week infant weighs more than 9.5 pounds.
According to my app, my baby is now around 6.3 pounds, and the size of a romaine heart.
