Fitting a Phil & Ted's E3 with a buggy board?

[mum2seb]

My Ds 1 is not the best walker (nearly 4, but has Spina Bifida - can walk, but tires easily). So I was thinking of getting a buggy board to put on the back of our P & T's. It looks as though it would come out quite far, though. I was wondering whether anyone has done this to theirs, or whether anyone has seen one? Is it 'do-able'? I'm reasonably tall (5'7"), but don't, unfortunately, possess the arms of a gorilla (would be quite handy), so was wondering how far back the board would come? Sorry for waffle! Thanks!

I trieed it and gave in when I realised quite how far it would have to come out to use the brake, also there is very little room for standing childs head.

Thanks - I think I've decided against it - I'm looking at getting a Maclaren or something similar and sticking a buggy board on the back!
