Hello all,I have a 2 1/2 year old & a baby due in December. I want to be prepared for the new arrival but am agonising over whether or not I need a double buggy. I'd appreciate your comments. Do you think a buggy board would do? Alternatively, someone has told me that clip on fold down seats are now available for pushchairs but I have no idea what they are called or where to start looking for them on the internet. Any ideas? All feedback gratefully received.
