This blog post highlights some of the concerns of parents about certain types of baby carrier, namely ones that dangle the baby from the crotch. – http://babywearingbuzz.blogspot.com/2008/05/why-bjorn-and-snugli-are-bad-for-baby.html
The ErgoBaby Baby carrier holds the baby in a different way – they are seated with their spine supported in a natural position.
The Ergo Baby Sling also gives great support for the parent too, so it is a win win situation.
The Ergo Baby Carrier is available from The Natural Nursery, starting at £89.99.
