BBC4 showed some old "Look at Life" films recently, documentary programs made in the 1960s.
In one of them, about children, it showed children playing in the street, skipping, playing hop scotch, making go-karts, building "dens" in play grounds and much more.
Children hardly do any of these any more, so there is very little "play" opportunities around for young children.
It is too dangerous to play in the street, and many of the activities I saw in that program would be stopped on health and safety grounds nowadays.
We child minded two young children over the weekend (one 12 the other 9). They both brought their iPads, and the older one brought their mobile phone.
When I went in to see if they had woken up they were both playing on their iPads and the girl was also texting on her phone.
The danger is if kids don't start school till 6 or 7 they will spend their time watching TV or playing on computers or games machines.
