my son is two years old and chooses not to talk. advice needed.

I do think that boys can sometimes not talk as early as girls... I think especially when they have older siblings that sometimes "talk" for them.  I wouldn't be worried at all if he seems to understand and can make himself understood.  I'm sure in time he will decide that talking will get his point across that much faster.  :)  My brother pretty much just grunted and pointed until he was about three years old.  LOL  But he's a very smart/normal grown man, now.  

I'm not sure if what to do in your case, though... I suppose you could tell him that you don't understand what he means unless he uses words... or give him the words... when he comes to you pointing, you can say "What is that... your head?"  "Your sister hit you in the head?" so that he hears, in actual words, what he is trying to communicate by pointing (and maybe you already do that).  I'd guess... that he'll just start talking when he is good and ready.  :)

I don't know about the boys developing later.  I have one of each and their language followed very similar patterns.  He may just be a late talker.  Are you raising him fully bilingual or just teachign him a few Spanish words here and there?

My daughter tried that I used to have to tell her "You will Not get what you want until you use your words and tell me what you want!" If she told me I'd get it. If she didn't I would walk away. Then she would chase after me grunting I'd say "Use your words" eventually she would give up and just tell me lol Now she always just says it. She is 2.

My son just turned 2 and does the same thing. He's alert and communicates his needs so I'm not concerned. I think some children jsut take longer to speak. My daughter didn't really start speaking until 2 1/2 and she is a huge chatter box now!

Younger siblings generally talk less and later. My yds just turned 3 and his language has grown considerably over the last few months. At some point he will decide that he needs to speak to communicate effiectively. Keep offering him ways to communicate without pressure but I would say you will likely see a big jump around when he is 2.5-3 yrs.
