Hi
I can double sling my girls now but don't do it very often. The logistics of getting them both from the car seats into the slings without one falling out, or bashing their heads on the doors or having one crawl away into traffic is just a nightmare! They are also getting a tad heavy so when I do it these days I put Zoe on my back and just carry Izzy but that is no good for shopping or anything but not so bad for a 100 metre dash from car to playgroup.
When they the girls were little we couldn't master the double sling, even though they would have been well light enough to manage. I had to wait until they could both sit up (which was fairly late for my girls) otherwise they would keep head butting each other!
Sorry I am not much help - my only suggestion is a get a pram that is easy to get in and out of the boot and not a nightmare to set up and drag around. But it is still a damn pain.... I am desperately hanging out until my girls are walking well enough to walk short trips like this... though I will probably regret that when it happens!
