DS was 55cm at birth (which I think was the 90th-ish centile). He then 'stabilised' for a long while on the 75th centile and was equal for height and weight. I measured his height today (he's just turned two) and plotted it myself and he's now around the 25th centile. I didn't weigh him but he looks an ok weight (not too chubby and not too thin...not very scientific, I know!)
He's always been a good eater, is fed a healthy diet, and I have no concerns about his nutrition. Equally, I have no concerns about his general development (his language is good for his age and his motor skills seem fine).
I'm just really worried that his height has plummeted down the centiles. DH is 6ft, I'm 5ft7 so I wouldn't have thought DS would be genetically predisposed to be small.
Should I take him to the GP?
