At what age should I start being concerned for my son who’s 14 and seemingly hasn’t started puberty? He came to me upset last night and it took a while for him to tell me it was because he feels like the odd one out amongst his friends because his voice hasn’t changed much and he’s shorter. Now I’m wondering, he is 14, is that not on the older side? Or am I worrying over nothing and he’s just a late bloomer?
