A five-month-old baby’s height of 67cm is generally normal. The normal height of a five-month-old baby is 62.5 to 69.9 cm. If the baby’s height is 67 cm and the neurological condition is normal, the height is normal and parents generally do not need to worry. Since five-month-old babies are in a period of growth and development, if they are breastfed, they should continue to be breastfed. May baby’s height is affected by genetics, environment, diet and other factors, and children’s height growth for non-equal speed increase, the evaluation should be based on individual baby’s own changes, not the so-called “normal value” as a “standard” for evaluation. If there is any abnormality, it is recommended to consult a doctor in time.
