Hi Babs :) In our area, Wheelchair Services issue both SN buggies (larger pushchair) and wheelchairs. We were referred by our physio when I mentioned DD2 was getting a bit big for her NT pushchair (she was 2.5 at the time).
At our appointment with Wheelchair Services, they showed us both the SN buggy and the wheelchair that were suitable for our DD2 (in terms of size, support pads etc), demonstrated their use (folding etc) and let us have a go with each round the corridors to test which we would prefer. From this we got an idea of manoeuvrability, weight, comfort of DD2 etc. All that was irrelevant though, DD2 wanted the wheelchair as it had a groovy design cover on the wheels :)
So we didn't get a SN buggy in-between because it was all on the same waiting list. Wheelchair Services have told us that if we do want to change our minds and swap the wheelchair for a buggy, this would be no problem and just to go back to them. So it's good to know the option is always there.
Oh and the SN buggy that we were shown wasn't the mac major. It was a different one but it really looked brilliant - robust and stylish. Our Wheelchair Services said they didn't do mac majors, but I can't remember the design they showed us, I'll try to look it out for you.
Welcome to the thread Babs It's lovely here, and I've learned so much from these wonderful MNers.
