DD2 is 2.9mths and 81cm tall. This puts her quite a bit below the 0.4th centile in her red book (she was just below at her 2yr check). I'm on the small side, as are my other 2 children, but based on this she's really little. I know it's not the worst thing in the world, but I also know it's not much fun being the smallest in your class. She's a pretty rubbish eater at the moment - grounds for hope when she improves, do you think?
