Can the carrycot be used without the seat during the first months? Would you recommend the X1 plus, Leclerc MP or [babyzen-yoyo-2-2|Yoyo2]]? Looking for a light traveller + city buggy. Thanks!!
As far as I know, it cannot be used without the seat - the seat can't be removed as a whole, and even if you tore down the fabric somehow, there would still be parts that would be awkward. It is a travel, occasional use stroller, and as such, the design is limited that (and other) way(s).
From your choices, personally, I would probably go for the Leclerc which feels like the better value for money, especially for such a small baby. That being said, I think there are better buggies for newborns in this size, especially the Ergobaby Metro+ or the Joolz Aer+.
