As portable tech devices like smartphones and tablet PCs become widespread, even small children are increasingly using them for play. This has caused some concerns among parents that they may get addicted, but at the same time it seems impossible to stop them playing with them altogether in this high-tech world.
The next best option is probably to look for quality educational apps to keep them occupied.
Tooth Monster HD incorporates a children's book and games, teaching small children to brush their teeth. It has three different mini games and a sing-along program, and enables children to read through the story while moving objects on the screen.
There is also an English-language version which parents can use as a fun way to teach their children some English.
