I have an ERGO and a peanut sling. The ERGO is great for long distances and back wearing but the peanut sling is my favourite for the quick trip to the shops. Easy on and off and I can carry him on my hip (he is about 10kg) and still be hands free. I find it hard to carry him without it now It is also good because I am pregnant and things around my waist are uncomfortable. There is nothing on my waist with the peanut and yet he is still well secured. And I can move him to the front for a snooze if he needs it.
