I wish I would have had this when my little one was younger but I bought it when he was about five months old, he is now nine months and it still gets a TON of use! I love love love that the carrier can go forward, onward, hip and back carry all in one! It's so comfortable and easy to adjust. My son usually falls right asleep. His legs are also supported so well in forward facing which was a MUST. I know this carrier is expensive but it is SO worth the extra money!
