There is no absolute standard value, the height of a 3-year-old 4-month-old female baby is about 93.8cm to 101.8cm, and her weight is about 13.11kg to 16.43kg. There is variability in the height and weight of three-year-old four-month-old female babies, which can be affected by nutritional, environmental and genetic factors, so the height and weight are only reference ranges.
