Rate of growth in teenage boys.
Our 15-year old son is only 1m57 tall for 40 kg. We are both fairly tall, at 1m72 and1m83. He hasn't stopped growing, I just think he's growing more slowly than his friends (4-5cm a year for the past few years). He has just had another sign of puberty, a 'breast' seems to be growing, which he is very worried about. Is this normal? Does it matter that he is growing slowly? Thanks very much.
It is quite normal for a 15_year old boy not to be very tall. He will probably have a growth spurt hen he starts puberty, which shouldn't be too much longer. Children who start puberty later are often taler as adults than their peers. Be patient, boys often don't stop growing until their early twenties.
The 'breast' is nothing to worry about either, it is relatively common and is normally down to a hormonal imbalance. If he is still concerned, make an appointment to see your doctor.
