I started using a cookiie Soft Structured Carrier when my son was 4 months old. Today at 15 months, cookiie pie SSC is still my savior when I go out with my baby. It makes something as basic as going grocery shopping with a baby so convenient and so much fun. The print is so cute, the fabric so comfortable, it's a product par excellence. I need it each day, for every time I step out with my baby.
PS - My baby accompanies me almost everywhere I go.
