Dear Adla,
Over the years - and babies :) - I've tried them all! My favorite is the SlingEZee, which is a padded sling. The key to padded slings is that they must be the correct size (one size fits all is impossible - the padding would get in the way of tightening the sling if the size is wrong). SlingEZee comes in five sizes. (Just a note - the basic sling sold at Babies R Us - I believe it's Dr. Sears's NoJo sling - doesn't work for so many people because they mass market it as "one size fits all" and that's impossible with a padded sling).
The Baby Bjorn is out of the question for you because it is so hard on the parents' back. Also, it is not good for the baby to be 'hanging' by their crotch (bad for their spine).
With your serious lower back problems, I encourage you to check out the ERGO. It is the most comfortable kind of carrier possible, because it puts the weight on your hips. Since the weight is not hanging from your shoulders, it will not effect your lower back. It is WONDERFULLY comfortable (which is why it's called the ERGO - ergonomic). Baby can be worn on your front or back. Baby is directly against you. Also, baby is not 'hanging' by it's crotch. The only negatives are that it will not have the 'ease' of putting baby in and out like a sling would, and that breastfeeding is not quite as discreet or easy in an ERGO. But I'm just not sure about you wearing a sling with your back issues. You'd have to be wearing it JUST RIGHT. http://www.nurturedfamily.com/baby-sling-positions.aspx

With all that I've learned about baby wearing through our family business, I'm also glad to help people individually. Baby wearing is sometimes not very intuitive, but the benefits are so worth it. For example:
Baby wearing...
... results in less crying for baby. One study showed that worn babies cried 40 - 50% less than the norm. Not carrying infants may predispose them to crying and colic.
... encourages language development. Placing baby on the level of adult conversation and eye contact is the perfect spot for learning.
... results in a secure baby. One study found that infants worn in a soft carrier by their mothers were more secure when left with a stranger.
... results in a more responsive mother. One study showed that mothers who wore their babies in soft carriers were more responsive to their infants' vocalizations.
... results in a happier mother. One study showed that mothers of pre-term babies who wore them skin-to-skin reported less depression than traditionally cared for babies.
... supports breastfeeding. Wearing your baby encourages baby to nurse and allows for easier, discreet breastfeeding in public.
... is great for baby's development. Equivalent to "tummy time," baby wearing allowing baby's balance to improve and muscles to strengthen as baby responds to mother's movements.
... allows the caregiver to have two free hands while providing comfort to baby.
... is great for premies. One study showed that wearing preterm babies skin-to-skin helped them cry less, have more quiet sleep, and maintain healthier temperature.
... is great for baby's digestion. Wearing baby encourages frequent, smaller breastfeeding sessions. This, combined with the motion of being worn improves digestion.
... is convenient for outings. Wearing your baby means there is no heavy carrier to lug around and no bulky stroller to navigate with.
... is great for mental and psychomotor development. One study showed higher scores for babies worn skin-to-skin on the Bayley Mental Developmental Index and the Psychomotor Developmental Index.
... is an easy way to lull baby to sleep no matter where you are.
... feels better for the parent. Carrying baby in your arms without a sling is tiring. Worn properly, a sling provides much-needed support.
... reduces instances of plagiocephaly (abnormal head shape). Wearing your infant means less time with pressure against their head due to hard carriers, carseat and swings.
Blessings,
R.
