I used to carry dd all the time as a baby in the summer on my front in an Ella roo sling (long woven sling) and loved it as she was close and secure and I was mobile enough to look after DS. She got a bit big and uncomfortable in it and at the moment I'm using a hotsling that I had previously, just to sit her more comfortably on my hip just for short times as its easier than carrying her. I would love to do little walks with her on my back in a rucksack carry, but I don't know how this works in cold weather with all the extra layers we both wear. Will she get too hot ina coat and a sling? Can I tie the sling over my coat? Is an umbrella enough if it rains a bit or can I only use it in good weather?
