Weight in the First Year

The idea
The average US newborn weighs about seven and a half pounds, loses five to eight percent in the first week, and regains it by two weeks.
In practice
Birth weight doubling by about five months, and a twelve-month-old averaging twenty-two pounds.
Where people slip
Averages vary by region and population; the weight lost in the first week is expected, not a warning sign.
