Do most 8 year old boys flit from one thing to another? No SEN.
I don't let them on screens all day (IMO they can't self-regulate at this age) but they don't do anything else for longer than 5 mins without coming to me. We have a decent garden and get out and about.
I'm more 'We've had a nice time playing now find something to do whilst I'm busy and I'll play at XYZ time' whereas DH keeps them constantly entertained.
Is this just boys with energy?
Guess who they ask for more!
