How do I position the crotch strap as my child grows?

As your child grows, you need to move the crotch strap to the slot closest to your child. The crotch strap should always be as close as possible to, but never under, the child's bottom. There are four positions: newborn position (for infants under 3.6 kg/8 lbs), rear slot, middle slot, and front slot. To reposition, loosen the harness straps, remove the crotch strap anchor from the bottom of the carrier, and insert it into the appropriate slot, making sure it lies flat. (Pages 76-79)
