If so- is it easy to attach and use? Is it lightweight? I'm looking for a very lightweight sling to use with my second baby as I'll have a toddler too so expect to be baby wearing a lot more at home than last time. I had a babybjorn sling and a wrap last time. Babybjorn is good for long walks but quite bulky and the wrap I found a pain in the arse to get on and off so probably won't bother with again. Thanks!
