If you want your baby to learn words before they can speak get this sign language book! It’s written as a story so you do the sign along side of reading the story! Sign language is considered vocabulary when meeting developmental milestones. Also, it’s never too late to start! We started at nine months (next baby I will start around three months) but my little guys picked up over half the signs in only two months of consistently reading it together. These two water color books are BEAUTIFULLY illustrated. One helps tie sounds to objects and living things and the other expands the vocabulary with simple words. The last book helps teach your little one body parts and their function. LTKBaby LTKKids LTKMostLoved
