A lot of books like that are meant for new first time moms. Think back to when you were a teen and babysitting or just starting out in daycare. You knew all the songs, nursery rhymes, etc. but you had to actually stop and think about it for a minute. For new moms it will have been years since they did some of these things depending on how much exposure they have had to other mothers. For them just having a list of ideas is not such a bad thing. Is it just second nature to most caregivers yes probably. It is the kind of book that makes a great coffee table type book for interviews where you can show it to parents and let them know that you will be doing "learning" things with their infant too. Sometimes it is nice to be able to grab a book and get the words to the second verse or the tune for a song you just can't remember. Not sure about the book mentioned since it looks like it might be ideal for moms on mat leave vice caregivers who get children starting care at a year old but for those that have never had the exposure at home it might be very useful. It could also be a good discussion book to use with moms at interviews to see what their attitudes are on play, spending time with baby and education methods.
