I have back problems too and find the Babyhawk the best as far as being comfortable and not straining my back. Not sure about bf'ing in it though as I used a Babasling for that but it did pull on my back a bit.
A stretchy wrap sling like a Moby would be best for you - you can bf in them and they spread the load out very well.
Important things with slings for comfort and tight and high - you want the baby right up on your chest. I note that virtually everyone I see with a BB doesn't have their baby in the right place. This also means you miss out on vital head nuzzling opportunities
Most wraps, Mei Tais and Soft Structured Carriers will give you MUCH better back support than a Baby Bjorn, but which one will work best for YOU and your baby is a harder question to answer.
For a newborn my personal preference would be a stretchy wrap, and you should be able to BF with one as well. I had a Hug-a-Bub for DD, and found it really comfy (although I never mastered BF in it) - as a comparison, when DD was 3 months I managed 10 minutes with a BB, but would carry her for a couple of hours in the wrap with no problems.
Can you get to a slingmeet? That would give you a chance to try a variety of different slings with some experienced ladies to help show you the knack. If you don't mind buying 2nd hand, its worth keeping an eye on UKbabywearingSWAP and Natural Mamas - you can get some real bargains, and if it doesn't work out then you can sell it on.
Wilkinet all the way here...was still using it last October/November when Dd was almost 2yo(on my back). It keeps baby really close to your chest, so supports the weight properly. I had no back ache at all whilst carrying Dd in it. It's like it makes baby part of you instead of an add on iyswim.
The Moby Wrap gets my vote. The fabric spreads really widely across your back so distributes the weight very evenly without causing any strain. My osteopath recommends it to all her postnatal clients after seeing mine. Honestly, you really won't regret buying a Moby, they are just fabulous.
It does have a bit of a learning curve, but you can just tie it once in the morning, and then pop the baby in and out. Loads of vids on YouTube. Hopefully someone will come along and link to the hunk wrapping his adorable tiny baby soon
Theres very little strain on the shoulder joint with a wrap, but obv your DH would have to take it carefully.
A one shoulder sling like a ring sling might be more suitable for him, but it would impede his good arm a little
Where are you ? Getting along to a Slingmeet would give you and DH a chance to try the different types and get hands on help with how to tie them
I watched it many times when I was learning to use my wrap . All for educaional purposes you understand. He does do it a little bit wrong, he should tuck the baby in the 'inside' bit of fabric first, but hell, he could have put her in upside down and I'm sure I would forgive him [drool emoticon]
I live near Worcester, but pass by Banbury a lot as my parents live S of Oxford and I have a big project in Oxford currently. Oh, and with the Cotswold line being closed this summer, we may have to get the train from Banbury..
Oooh! I watched that vid many times too! yummy! I wonder if he knows that women droooooool over him!
CMOT, do you use the Moby with your 3yo? I would love to still sling Dd(2.5), and the last time I carried her was a bit before she was two. I used the Wilkinet which was a bit 'short' for her, but otherwise great and I made a non stretchy one myself too, but I think there was just too much width in it.
i also got sore after baby bjorn for a few weeks. had dreadful back thru pregnancy, saw a physio etc. on recommendation from a friend i got a 'kari-me' and i have loved it. never a moment's pain. used it til he was almost 18mths it was that good! good luck
