I had a sling, but was never shown how to use it for a newborn & as u said Bodhi just seemed to get lost in it. In th end i just ened up using my hand me down baby bjorn.

Have you been into a shop where they sell the ergo? I went to try mine on b4 i bought it just to make sure it was what i wanted & needed(its awesome might i add). That way you can see if the insert is flimsy or not.
