A double wheelchair buggy for boys

I'm hoping to raise enough money to be able to buy a wheelchair double buggy. This would mean more freedom. Outings would be easier, more achieveable , more comfortable and safer for all :-) Owen has an extremely challenging journey ahead and to be able to let him live life to the max I need to be able to take him and his brother out safely. Owen has had over 30 procedures / ops on his heart along with many other medical procedures and when he's well and home he deserves the best x
