It would have been helpful if you gave me your daughter's actual height as well. You say she towers above other girls of her age and it is possible that her weight is in balance with her height although this does appear to be unlikely. Her weight is certainly far above the average weight for a girl of almost 6 years which is 20kg.Her weight is on the 98th percentile line of the growth chart for girls which means that she is in the top 2% for her weight for girls of her age.You mention that she has a big tummy so it is likely that she is indeed overweight even if she is very tall.It would be best to consult a dieteician to advise you about her diet as this is the time to sort this out with her starting school.
