Am currently pregnant due any day and just visited a friend with a 2wo. She had on a sling with rings at the back (2) in a stretch material but she was wearing it as a cross across her body at the front with the baby on her front in the middle and then the rings behind her shoulder blades with the ends hanging down behind her shoulder.
It looked EXACTLY like what i've been looking for - I have tried a proper wrap out at ante-natal yoga and I felt so claustraphobic, like I was wrapped up like a mummy (the egyptian kind, not the kind i'm about to become :) )
Hers was really easy for putting him into and taking him out of and it was made by a brand called 'close' - she got it 2nd hand and said there are loads on ebay but I can't find it online and all the pictures of ring slings online show them with just one set of rings at a single shoulder (and an older than newborn baby in it).
Can anybody help???
