Testosterone surges in boys

[sayitwithme]

I have been googling this and it seems that these surges happen when they're sort of 4 onwards. Is this true? I'm asking as someone suggested that little anger bursts from my baby (7 months) might be due to testosterone surges. I'm thinking it's probably just the usual baby frustration/teething/belly/alloftheabove issues.

I also think that it was from 4 ish onwards. Both my boys had some changes (mostly physical) at about 3.5 - 4, with more 'agressive' behaviour. The physical changes are obvious (growing very fast, hungry all the time, and their 'willy' standing up as they say!!!). My 3.5 yo DS came in the kitchen the other day with his knickers around his ankles and said look mummy my willy just woke up!.

7 months is too young for that as far as I know.

Yes that sounds just like the usual baby outbursts, that most babies have, boy or girl.
