Voice breaking

[Posey]

What is the earliest a voice might break? Unlikely or impossible at primary school do you think?
Just had a conversation with dd as a friend at school reckons another friend's voice is breaking (it isn't) but just set us wondering how young is it possible?
TIA

A boy in year 6 has a voice mid-break.

Felt for him when he had to sing a capella at junior concert this week.

Awww

My DS's (sept baby) started to break Yr 6.HIs teacher said his voice kept croaking in class. He is 12 now and it went completely about 2 months ago.

my DS is 13 nest month and his hasn't broken yet. But he is small and I think that makes a difference.

Went to ds's school today and he is a lot taller than the other Yr 7's and a lot of the Yr 8's. I think he is about 5'7

Thanks for that!
