Babyzen yoyo is light and compact. Will be quite easy to push around with 1 hand if u need to. Carrier i am not sure..
Doona, as sometimes you might need to grab so it is more convertible and quite lightweight as well.
Keenz for stroller. Konny for 2 Month old baby.
Doona! It can act as a car seat too
