Height dropping to low percentile - growth hormone deficiency? Hi everyone, wonder if you can give me some reassurance? Zachary had his height checked today for the first time in six and a half months (he is now 15 months). It has gone from the 9th percentile to 0.4. He has only gained 5cm in all that time. Both myself and my hubby come from shortish families and we are not tall ourselves.
