How often is it necessary to check a toddlers height and weight?

Whenever you make a visit t a doctor for her general health check up, you can do his height and weight. And if the doctor says that the kid is reaching his developmental stages on time, there is no need to check it often. Otherwise also, there is no need to freak out if the kid is short in height or have low weight. Every kid take their own time to reach his/her developmental stages. As long as the kid is healthy and active, it is all good.
