Apologies if this is in the wrong topic.
I am thinking of getting a Boba Air sling for my toddler. We used to use an Ergo quite a lot, but these days I always seem to need to take a pushchair out (because we walk / use public transport everywhere, and DD is heavy and seems to require an ever expanding amount of paraphernalia, so I just can't carry the whole lot). The ergo is a bit too bulky to stick in the bottom of the buggy and is a bit sweaty on a hot day.
So, I have been looking for a lightweight sling and I am thinking about getting a Boba Air because it looks like it packs up really small. I imagine when dd gets a bit older and can walk further distances I could just put it in my handbag in case she gets tired and needs carrying for a while, and we could ditch the buggy again.
However, my local sling library doesn't have one so I wanted to get some views on it before I splash out.
I a size 12 and short and have the ergo straps on their tightest fitting, if someone who is a similar size and shape to me has used a Boba Air I'd especially appreciate your feedback 
TIA.
