I read this book as part of my Infant/Toddler Montessori teaching training. This book has its pros and cons but overall is very useful for parents, teachers, and anyone who spends time with babies and/or young children. 

PROS:
- Upholds Montessori's view of the child as inherently good and worthy of genuine respect from adults (takes small persons seriously, sees them as legitimate human beings)
- Points out many ways we unintentionally impede the development of infants and young children in a nonjudgmental way (seeks to educate, not blame)
- Advocates for inexpensive, simple, and practical materials rather than manufactured toys or high end equipment 

CONS
- Sometimes contradicts itself, further clarification needed on some subjects 
- Dated language/perspective around gender and intimate relationships (puts hetero, married parents as the default and ignores a lot of lived experience and variation in how children are conceived, born, and raised)
- Positions breast/bodyfeeding as the only good way to feed a baby (ignores the vast number of parents and caregivers who are, for what ever reason, unable to feed in this way)
