I loved mine, wore DD2 til about 4 months then I found she got a bit heavy for me and it would loosen abit. I do still wear occasionally but not for long periods.
But for the newborn stage it was fantastic. She would go off to sleep or just be so calm and settled within seconds of being in there. And made life alot easier to get around doing things with DD1. I kept wishing I'd had one for DD1.
