There's a range of normal heights and weights for toddlers.

Growth charts are used to track the range of normal height and weight for toddlers and children. At every age, there's a range of healthy measurements and unless your child is consistently out of the normal range -- below the 10th percentile or above the 90th -- there is most likely nothing to worry about.

17-month-old boy

According to the Royal College of Paediatrics and Child Health growth chart,17-month-old boys have an average height of 104 cm, with the 10th percentile about 98 cm. The 90th percentile is about 109 cm. The average weight is 10.8 kg, with the 10th and 90th percentiles at 9.4 and 12.5 kg, respectively.

17-month-old girl

According to the Royal College of Paediatrics and Child Health growth chart, 17-month-old girls have an average height of 103 cm, with the 10th percentile around 97 cm. The 90th percentile is around 109 cm. Their average weight is slightly under 10 kg, with the 10th and 90th percentiles at 8.5 kg and 12 kg, respectively.

Significance

One measurement outside the normal range is usually not a reason to worry. Doctors are more concerned with repeated abnormal measurements or wildly varying measurements.

Considerations

Head circumference is often measured at checkups. Like height and weight, physicians look at a collection of measurements over time.

More information

Most 17-month-old toddlers walk with ease and even climb. Most are still ambidextrous, although they may begin favouring to use one hand. They may also begin to protest naps.
