Our COMPLETE™ and Pursuit™ models offer both a narrow and wide seat setting to support your baby at every age. The right time to switch to the wide seat setting depends on the size of your baby. If you are wondering if your baby is close to being ready, give it a try!
First, put your carrier in the wide seat setting. You can watch a video on how to this here: Adjust to Wide Seat
Then, put on your carrier and place baby inside. Baby's legs should be supported from knee to knee and legs should be able to bend freely at the knee joint. Ensure your child's legs are bent at a 90 degree angle once in the wide seat setting. If baby's legs are still extended (even slightly!) at the knee once in the wide seat, baby is not quite ready. Wait another few weeks to a month for baby to grow a bit more and try again!
