* Some experts say the heartbeat should be in the area of 135-145.

However, some say that the heartbeat is associated with gender: that of a boy is rated at 145 beats per minute, and that of a girl at 160 beats per minute.

* I agree that 135-145 beats per minute is about right - for both sexes for young infants. The heart-rate will generally decrease with age through childhood. (The adult heart-rate is 70-80 beats per minutes.)
