We bought the ERGObaby because he sounded very promising. I am of the personal view that the Ergo Baby is good, but like our little do not like him. The procedure they cram in this newborn use her at all do not like.
Therefore: The idea is good, I would again buy the ERGObaby because you can use it also great for later. However, for newborns, he is in my opinion suboptimal. It works, but not as well.
