Hiya.. My son of 3 yrs old will be starting nursery september this year, he loves playing games on phones so I thought to buy him innotab for his b-day which is a touch screen console that teaches them things while playing the games... Its aged 4 to 9 years.. Is this a good idea or am I pushing him to early? Just thought he would really enjoy it but they are expensive so don't want to rush into buying.. Any comments appreciated!
