My girls are in P2 and N2. Both are diligent and obedient girls. They do well in their studies and homework. However recently my wife found out that my elder girl just being to occupied with youtube only to the extend she hides or forgotten about her homework. We have stopped mobile access to youtube but she will find another way to watch. This has been a worrying trend and we wanted to nip the problem in the bud. We can stop youtube forever..but appreciates if anyone has other recommendations.
