I have an Ergo which I used for both DCs until they were well over 2, but never quite as comfortable with the insert when newborn.
Am pg with DC3 and want something to do me until I can use the ergo without the insert. I am a novice with any other types of sling, but I doubt ring sling is right purely because DH will need to use it and he won't want loads of fabric hanging down!
I'm 5ft 6 and will have massive boobs (34k during past bf experiences!). DH is 6ft 2 and very slim. So the carrier needs to suit two very different physiques 
All suggestions gratefully received!
