I love free printables, and anything that helps me teach my kiddos their alphabet is a win for me.  I do recommend laminating them if you plan to let your toddler touch.

For those of you with a child on the Autism Spectrum, I recommend making these cards a little more stimulating by adding textures on top of the lamination.  Glue glitter, fuzzy fabric or puff paint on them to give your ASD child more stimulation.
