I am child physiotherapist and actually totally against baby carriers out of line BabyBjörn - this harm the baby more than they do him. Now, with my 3rd child, my sling was too inconvenient (located at tying on the floor, not necessarily hygienic - and is in the summer except hot only hot) - I was looking for a good alternative - and came across the Bondolino of Hoppendiz. The carrying method of a newborn baby with his legs inside it behagte not me very (baby slips over time down and "stands" on his feet) - but the fact that I had a very large newborn (birth weight 4600g), I already had it from the in the "normal" carrying way contribute 5th week - as seen in the photo, with "dangling" legs.
Since the newborn carrying method is not very mature, there is a star trigger - otherwise really great! Note: the spine of newborns is anyway not yet ripe enough to be loaded in an upright position for more than 15 minutes Carrying Aids - They include all baby carriers, also the sling !! The steps the parents additionally compress the spine of small dwarf too much. So please be careful!
A small drawback, there is - the Velcro closures of "hood" make a murder-noise at opening, so that the (sleeping) baby startled and wakes. On the other hand you can with this exact Velcro hood really will optimally adapt to the baby's head - so this is the same time also a plus; o)))
