Puberty in boys

[pj67]

Hi. My son is 13 and I have noticed that some of his friends seem to be getting taller and have deeper voices etc. I'm not noticing any signs yet in my son and just wondered if that was okay and what are the first things I would notice.
Thanks

My son is 12, and his voice hasn't started changing yet, he hasn't grown much the past year though he is 5'2". My nephew is 13 1/2 and he is just 1/2 an inch taler than my son, but his voice started changing around 6 months ago. I thought he had a cold, that's what it sounded like.
