Hi all, I just bought the ergo sport carrier but didn't get the insert. DD is 2 months old, and seeing as I am only planning to be a casual carrier user (for eg. supermarket shopping so I can push a trolley instead of pram) I'm not sure it's worth it for me to buy the insert to use for only a couple of months...

So I was wondering if anyone had tried alternatives that worked? For eg, using a blanket etc? Or would that be no good for the baby's posture and neck? Otherwise I can just wait until she's big enough for it

Thanks in advance!
