YANBU yw early moving or not is no reflection on the intelligence or future abilities of the child. In fact being an early mover is, as Detective knows, a big PITA. I was v chuffed that DD1 was so late (not worryingly so except for my MIL) and have been slightly annoyed (though proud of her achievements) at LO's huge mobility leaps the last few weeks as it mkaes everything harder work!
I hate competitive parenting, especially when people resort to massively exagerating or outright lying. My MIL is a specialist in this. Her children were walking talking toilet trained reading writing geniuses by the age of 12 months dontcha know. 
I like waiting for the next stage. As much as I whinge about being at home with the kids I love, love love watching them develop and change at their pace, and wouldn't speed it up for the world. Each little first is to be savoured, as it, as a first, will never happen again.
