The Caboo Close carrier is fabulous.
Can be used from Newborn upwards without extra inserts like the Ergo needs
Is 'semi-structured' so you don't have to wrap and tie multiple times like the Hugabub
Holds the baby's bum and hips in the recommended position unlike the Baby-bjorn
Baby can face in and face out
Is organic cotton so breathes
Very neutral colours so isn't overly feminine like some slings so Dh loves it too!
Having said all this - I plan on buying a Manduca or Ergo in future so I can keep wearing DS into toddlerhood
