I feel like i've been living under a rock. I've just stumbled across an entire network of Babywearers. The name says it all, it's mothers who go about their everyday life carrying their bub in a sling. Even older children at age 4 and up. I have no idea what the age limit is, guessing it would be how much you can carry. I had Stevie in a sling all the time when she was little and I have to say I loved it. When she was 2 days old (fresh out of hospital) we put her in the sling and walked to the main st and probley did some grocery shopping. I used it with Lochie but not as much, why i'm not sure. I haven't used one with Jimmy just because a friend of mine told me there was a program on about the use of slings leading to deaths. So i was scared off but all the ones here look very sensible.
I found all this at Marvelous Kiddo so I would recommend having a look at this amazing blog. Also lots of really positive parents sharing experiences and I found reading it all very uplifting.
Here's some examples of baby wearing.
