A quick question on child language acquisition

I just need to back up my facts - and whilst I love me a bit of the ol' Wikipedia for internet TRUFAX, I just want to make sure that I am correct.

When a child starts to babble, what order do the sounds come? I'm arguing that it's m, b, p, first followed by d, g, t, etc. However I've been called out, because apparently some baby book says it's 'd' first.

Is there are general order?
I can has a grammar now?

Is there a common order to how babies start to make noises?
