    Cute, don’t stay on well
    Size: 12-18 Months Toddler, Color: White Leather
    I love these for the look, comfort, and flexibility for a new walker. Her teachers complain that they come off easily, which we did lose one because of this out and about. We graduated from these to similar ones from striderite.

    Perfect shoes for early walker
    Size: 9-12 Months Infant, Color: Eliza Pink
    The Robeez First Kicks were the perfect solution for 10-month baby girl who is starting to walk with assistance. She walks barefoot at home, but we wanted a solution for the times she is in public places and wants to get down and walk a little. The shoes can be worn with socks to keep her feet warm when it is cool outside.
