The 43-year-old actor has two kids, Jaden, 13, and 11-year-old Willow, with wife Jada Pinkett Smith, and he said that he and his spouse are constantly in dialogue about what is best for his kids, reported Daily Mirror online.
"Willow had a huge record called 'Whip My Hair' and then she just cuts all her hair off and I have to, 'Ah, your mother says I am OK with that sweetie.'
"Y'know the most difficult part of the whole thing is emotional management. Jada and I have been talking a lot about whether you pull back during the teenage years because they are very formative years for Willow," Smith said.
The actor, who also has a son, Trey, with his first wife Sheree Zampino, managed to convince his daughter she should concentrate on her already successful music career.
"She's been supporting Justin Bieber on tour, saw a Russian ballerina and was riveted. She was like, 'I wanna go home and take ballet.' No honey, you've got to settle more tour dates. So now she is way gone on ballet," he added.
