Hi, there is 14 months between my boys. We bought the iCandy Pear from scratch and it was such a waste of time and money. I thought it was the best double I had seen, all the others didn't have the option of baby lying flat, or the toddler seat wasn't adjustable. In reality, it was so cumbersome, a pain in the neck having to dismantle it to collapse and put in the car, an inaccessible shopping basket and it was almost impossible to steer! Furthermore, my oldest son managed to bite a chunk of foam out of the bar, and I heard nothing when I complained about this to iCandy. I think if you already have the Apple, it might make sense to buy the converter kit to make the Pear, but otherwise don't bother! It might be worth asking yourself if you really need one. We sold our Pear when our son was about 21 months, as he wanted to walk everywhere anyway. We had kept our single pram, a Mamas and Papas Skate and he sits on the tray part of that when he gets tired. I thought we would use a tandem for a lot longer, but I was proved wrong! Good luck!
