Having used a capsule, I would never not have one now! We were lucky enough to be given one by friends, but as Lucy says, you can hire them quite cheaply. My mum hired one for her car for 6 months and it cost $100 all up. I have been told not to turn DS around until 12 kgs or 12 months, apparently that's the latest recommendation. So we've now got him in a reversible car seat.

But I loved the capsule, and was sad when he didn't fit in it anymore. Would definitely recommend having one.
