DS's growth has slowed down / stopped. He has gone from being one of the taller children to having numerous children who were shorter than him grow up past him in the last term.
His height seems to be dropping down the centiles charts:
2y9m 62nd centile
3y2m 76th
3y8m 73rd
4y0m 66th
4y3m 66th
4y4m 62nd
4y11m 42nd
5y1m 54th
5y6m 38th
He has only grown 0.5cm in 5 months.
Would you see a doctor about a growth pattern like this?
