My lovely lil Rebecca will be 9months on 3rd Nov, and she still isn't crawling. She tries to do it, but when she can't she goes into a fit of temper, or starts rolling about to obtain things. Should I be worried? Her nursery say she is a "clever cookie" with words etc, and today has started saying "stinky" after my mum said you've done a stinky jobby (thank god she never repeated the latter!") The nursery have no concerns and say she is advanced with speech etc. Is she just like her dad and just a lazy bugger?
