Learn-Along Leap, made by LeapFrog, is a fun toy for toddlers. I used it with my baby to keep her entertained. He is a small, soft plush toy with a hook/clip so you can easily attach him to the diaper bag, car seat, or stroller.
My daughter loves the alphabet song so she always loved when Baby Leap would sing it to her. This was especially useful to keep under our changing table and pull out during diaper changes. My daughter was soon enough requesting "Leapie! Leapie!" at every diaper change.
I only have a couple critiques of this toy: 1)it is a little hard for babies to press Leap's tummy so I had to do it for her for a long time. She can press it and activate it on her own now easily at 18 months. 2)It only sings the alphabet song, so if you are looking for variety, this is not the toy for you. If your child love the alphabet song and singing ABC's, they will probably love to carry Leap around and sing along with him. It is an affordable toy to keep your child entertained if they are interested in it.
