What problems may parents face during the transition that occur during adolescence?

The problems are endless to say. Teenage pregnancy, drugs, anything really. The transition that occurs during adolescence is the biggest transition that occurs in ones lifetime.

Well they may
argue more
understand each other less
yell more
socialize less to each other
lose understanding for some time
experience frustration and anger

But that's the wheel of life. Hope this helps!

Well a pediatrician is a children’s doctor and a obstetrician is a doctor that delivers babies and cares for pregnant women.
