This book has cute pictures and is fun. My 33 month old daughter likes the piggy playing peek-a-boo, and being too busy for binky. She was interested in piggy finding binky and focused on him needing to get it back, so I don't know that it helped her get rid of binky. She does like to tell piggy how he's big now and doesn't need it, so maybe it helped. I'd recommend "Binky Box"- my daughter decided herself to put her binky to bed all day. She loves the box she created and takes it seriously that her "friend" cannot be kept up all day! She was a major binky addict, so I can't believe this book worked. Piggy book is still nice to use for extra encouragment in giving up that binky willingly.
