I just very reluctantly returned a Boba 3G sling. I loved it for Baby (3 months and too heavy for retro Baby Bjorn that I have, which sits all on your shoulders instead of additional waist support) but I felt like the straps needed to be clipped together at the back, and one buckle seemed to rub under one arm as I walked.
I'm desperate to get a new one but unsure which. The next local sling meet isn't for weeks.
Any suggestions?!
