I think you're ok with the one who is 2.5 mos older than him, as long as the other child isn't speaking FOR him. My nephew started talking later because he had 4 older siblings and didn't HAVE to talk. One of the older girls never shuts up, so he probably couldn't get a word in. LOL
I was beginning to think my DS might have a speech delay, it took him forever to start really talking. Right after he turned 2 it seemed his vocabulary simply exploded. Now there are days when I long for 5 minutes of quiet. (he's 2.5)
Also, in bilingual homes, kids typically start talking later. They don't have any delays once they start talking, it just takes a little bit for them to start. My theory is that they are still absorbing as much as they can of both languages before they start speaking. It's definitely easier at that age to learn two languages and being bilingual has become a big asset when looking for a job in some fields.
