Spelling Errors
Format: Paperback
This would have been a great book; however, it literally had spelling errors including one on the back cover. Disappointing. It was a gift for someone but it’s not even worth returning.

Learning Fun with "See, Touch, Feel: 123"
Format: Board book
"See, Touch, Feel: 123" is a fantastic addition to our bookshelf! My baby loves the interactive touch-and-feel features, which make learning numbers so much fun. At 10 months old, my baby enjoys flipping through the pages and feeling the different textures, all while being introduced to counting in a playful way. This book has been a great way to engage my child while encouraging early learning. I recommend it to all mamas with little ones eager to discover the world around them!
