Hi all, we’ve purchased a Maxi-Cosi Mica Up car seat and realised today that it is for babies 4 months and above! Maxi-Cosi do the Mica which is for newborns, with the difference between the two car seats being a newborn insert. It appears Maxi-Cosi do not sell this insert separately. Does anyone have one for the Maxi-Cosi Mica they no longer require? Thanks 😊
