Hi! We live in flat near London, no lift, narrow stairs and no space downstairs to leave pram. I am searching for some option that would be suitable for newborn. I am planning use sling but I also want some option on wheels. Plus we travel a lot (flights) so it should be quite foldable and small. I have been looking at Babyzen Yoyo but we are so tall with husband and it seems ways too small. Maybe Babyjogger? I want to avoid paying too much just for the brand (no iCandy thank you). Also I don't want to buy 2 different, we don't have space to store it. Do you have any suggestions or experience? Thank you.
