hi there , you probably think i am crazy, but after coming across Kanga training and after DS1 could not lie on his back / was not that comfortable in a buggy, I am looking for fitness classes where I can "sling" DS2 (to be born shortly). Does this exist in Surrey? I am based in Esher. The buggyfit classes are very specific that they do not want Babywearers due to posture reasons. I could not find anything on the net. Cheers
