My friend is an OT and came to playgroup to discuss this recently. She said milestone ages for boys were around 6 months later than girls. Having said that Matilda says heaps of words, and some of her words are the same as Aidyn, nanana, bapple and things like that. She may put 2-3 words together occasionally and sometimes she signs instead of using words. She talks and babbles incoherantly heaps though and gets frustrated when we don't understand her. I've been told this is all completely normal for her age group by the OT.
