I'm hating the horrible sweaty boobs on bump sensation too. Ick.
As for baby wearing - Baby Bjorns thrive on name alone. They are overpriced, really pretty uncomfortable for you to wear and actually they put baby in a position which isn't safe for developing hips (if your baby is at all at risk of hip dysplasia) so if you want to make sure your wee one isn't going to spend months in a full body cast - I'd really avoid like the plague. There's a reason they are given as hand-me-downs they have crap resale value. Sorry for bonfire pissing but Baby Bjorn carriers are one baby product that make me really cross. So if you have one and think baby wearing isn't for you - try another carrier from the sling library. Most of whom will simply not stock Baby Bjorns as they're that poorly regarded.
When it comes to where you wear them - it's a very personal choice. I found baby wearing indoors muuuuch more use than outdoors actually, as whilst hey we'd all like them to gurgle peacefully in the Moses basket whilst you get stuff done - newborns don't as a rule, get that particular memo and if its a choice of getting stuff done with a happy baby strapped to you, not get it done whilst holding a baby on the couch or do stuff and listen to your baby scream themselves redder and redder until they puke - option a) wins!!! I do think that's the biggest difference in expectations between before having a baby and the reality - you think you'll have much more control over teaching or disciplining them to get used to not being held than actually you do have in reality. Certainly when wee they are often very distressed when not physically on you. And no matter how long you try to let them get used to not being held some will just scream blue murder until they are. As a pal said to me 'they only have one argument and it's very compelling' 
. So if you find that you aren't achieving some housefrau ideal of achieving lots of stuff or exercising and reclaiming your pre baby figure, whilst baby sleeps - don't feel bad. Read 'What Mothers do' for a really realistic insight into the first few months. Velco baby and stuck to the sofa is often the reality but it doesn't last forever. You kinda have to slow down your expectations and pace of life. God knows how I'm going to achieve it with crazy climbing toddler sidekick though!!!
I found going outdoors with a buggy was more practical for us personally than baby wearing as baby can nap in it leaving your hands free for a coveted hot cuppa, its easy to take your coat etc on and off without having to take them off and wake them, its somewhere to hang the change bag and shopping bags to save you carrying them and there's no risk of falling over on ice and landing on your baby.
But the sensation of going out and about with a wee baby strapped to your chest in a nice handy position for kissing their wee heads is AWESOME too. I can't wait for that actually!
As for the NHS chat Puppy I agree with everything you said. If you look at the performance metrics the NHS is kick ass even compared to some of the priciest private systems around the world. Discontent against the NHS is politically motivated and largely related to deliberate underfunding (despite lots of forewarning of the baby boom cohort approaching retirement and its most expensive healthcare years) to allow whole swathes to be privatised. I think one of the biggest problems isn't due to the public nature of the NHS but actually down to the 'arrogance' of some medics (especially GPs) - they're a bright bunch but many don't actually keep up to date on CPD issues once they get to a certain age / seniority and assume they know more than anyone else.
Sorry epic post!!!
