We finally decided to bite the bullet and try to solve the technology additions in the household today, by swapping the current office for the playroom.
The thinking being that if we give the biys a place they can go to relax and play games and / or meet their friends that is their own haven, then they will not just be gaming, sleeping etc in their rooms and perhaps most importantly allows us as parents to better monitor the time that they spend in each activity.
The challenge that it poses us of course is that we now no longer have an office at the bottom of the garden as it is now the playroom.
We have therefore setup Vicky with her office in the attic and Simon will be using either the dining table or the bureaux in the lounge on the days that he works from home (he is looking to increase his days in the Leeds office over the coming weeks).
Hopefully this will work out for all of us in time.
