This detailed video explains the procedure to install the Infant Sling Child comfort accessory by Chariot. The Infant Sling is used to position an infant in the safe and proper position.
Yes, I have a CX2 as well, bought brand new about 3-4 months ago. My husband installed the Infant Sling (new from the store too), he's a mechanical engineer, very detail orientated person. That's the exact video he looked at first Well, my baby HATES IT to no end! I felt so frustrated! She didn't stop crying until I picked her up from that sling! I kept adjusting it and re-adjusting it myself countless times! Right now, when I get closer to the over $1500.00 Chariot she starts crying! Ugh!!!
Be carefull, this is the oldsystem, the new carriers from 2013/2014 have an another beltsystem. You cannot combinate the old infant sling with a new carrier.
On the official Thule channel I read in a comment by Thule that you can put two slings and later two baby supporters (black bumpers) side by side in a two kids carrier.
