Will any newborn pack fit the Yoyo+ frame?

Hi, Laura,

Pretty much all of the newborn packs should fit it - expect for the separate bassinet, which, btw I think, could be put on, too, with the attachments system/adaptors. There is a slight change in the canopies but I don't think the attachment system of the hood changed. So, yes, you should be able to use any insert newborn pack, I believe, as the PLUS has a reversible backrest.
