Speech has been an issue with both my both especially S4. He didn't say mama until he was 2 1/2.
This is something not to take lightly. Any speech issue spills over to late development of English Language skills. I only know this because this is what happend to S7 and he HAD speech. S4 is still struggling some, but I have decided not to start him in K until fall of 2011. He is a November baby and it just makes sense. I did it with S7 too and im thankful I did.
Now for your wife to ignore or gloss over this is total irresponsible thinking. I cannot stress how important handling this now is. This again shows you what kind of person she really is.
I hope that the Teachers enlighten her, I would like to be a fly on the wall in that meeting.
Good luck and let me know how you make out!
Oh, and its totally normal for the older sibling to interpret what the other is trying to say... its happend to us all along.

Happiness can be found, even in the darkest of times, if one only remembers to turn on the light.
