I hesitated before buying this book wondering what we could do "Montessori" with a baby and I would have done better to listen to my instinct, because the answer is obvious: Nothing particular, at least nothing that required a book! Besides, it is written so big we can only have that feeling of filling attempt. If you already know you Montessori will not learn anything at all and if you do not know Montessori but that you know the basics of what babies do, namely play with mobile, balls, soft toys, rattles etc. you will not learn much, nothing with advice for enlightenment and for the few Montessori concepts are not so developed as succinctly as you will be forced to buy another book, so forget that one counsel and go directly buy "Awaken, flourish, encourage her child, Montessori pedagogy at home" here you go down to it at least! Another book that surfs Montessori for not saying much!
