A childs language development is strongly influenced by the close sharing of well-known songs and rhymes, and actions and movement aid coordination. Motor skills are closely related to language skills. Encouraging action through rhymes will aid language development.
Let me give it to you straight on Five Little Ducks. This book was rough for me. In my family we are big fans of the song and I thought this would be a fun way to practice the accompanying ASL.
The two issues I had with this book:
1. It requires at least two people to read. If you want to use the ASL when singing along to this book, someone else has to hold it, ideally another parent. Not a dealbreaker since I have a partner, but not the best.
2. The layout of the book is strange. Rather than taking you through the whole song, it gives you the initial refrain and then you have to page back to the start and continue on (with the number of ducks slowly dwindling).
I did enjoy learning more ASL to practice with my boy and I imagine that it could be fun if he was older and able to make the signs himself as we read along. With all this in mind, it is not a horrible book option but probably not for babies (unless yours is a baby prodigy).
This is written in English, but the illustrations include instructions for a few simple words in sign language. A tune for the words is included on the back cover. It's a fun board book, with larger pages than most board books.
The kids weren't into the book. Even though I read in a sing song voice and with gestures. We gave it 3 tries before returning the book to the library.
Maybe we T.R. gets older I'll borrow the book again and try to read it to him.
