? 14 g/dL to 18 g/dL for men
? 12 g/dL to 16 g/dL for women
A child is born with a high level of hemoglobin, in general it is more than 15 g/dl, and it starts to decrease slowly during the child's first months of age, reaching 9 g/dl by the time the child is 3 months old. This levels then start to increase back gradually, to the point that when the child is 1 year old it is normal that it has reached 12 g/dl or more. After adolescence, a normal value for a boy is 13 g/dl and for a girl it is approximately 1 g/dl lower.
I got most of this info off of websites.
Have a good day!
