I think you would need the newborn support at the very least. It's sold separately but is a LOT cheaper than the carrycot, so you could start with that and if you weren't happy then you haven't wasted much money.
Should also add, there is a little window in the hood that you can peek through to keep an eye on your baby. We have a nipper sport for our older baby and I was a bit unsure about the world facing position, but I found it fine.
Completely up to you, I'm looking into getting this pram too as also have a 2 year old and a baby due January. I think I would feel happier if baby was in the bassinet facing me. I've found it on uberkids for 529 for the double plus carry cot. I just want to try it out somewhere before I go ahead and buy it.
