Looking for some help - again!
So I went and bought a Bugaboo Bee+ and I'm really excited! 

I was going to buy the newborn cocoon at the same time, but thought that £55 (the cheapest I've seen) or £67 was quite expensive based on how long it'd be used for, so I'm looking at 2nd hand on eBay now.
My question is, are all the cocoons the same size or does it depend on when they were produced? It's just that I read elsewhere that the cocoon that was available before the Bee+ is possibly smaller than the ones produced now along with the Bee+.
I hope this makes sense! I'm 34+5, it's late and I'm not sleeping well!!
