As a crunchy nontoxic mom to be, this book was extremely validating to me. I made my husband read it and he quickly switched to also caring about organic produce, avoiding microplastics, and using nontoxic household products (especially when pregnant). This book is full of scientific research and has so many modern references proving the dangers of what so many women are told is okay in America. Bonus points because she does it in a non-pretentious, non-condescending way and even acknowledges the limitations of trying to avoid some toxins in pregnancy. I would absolutely recommend this book to any pregnant woman!!!!

I feel like I know more than my doctor at this point. Highly recommend. No one else can advocate for you and your baby more than yourself!

10 weeks to go! I started this book as soon as I found out I was pregnant and it’s been super helpful. 4 stars only because this year I’m changing my reviewing approach so that 5 stars are reserved for lie changing books only

Helpful for those who read ISWTE and are trying to navigate early pregnancy. After 3 losses I wanted to take some sort of control back, even if it’s just taking the supplements recommended in this book. Would love to see more data and commentary about whether things like gardening/hot baths/travel are safe.

Clear Research, Easy to Understand

I appreciated the research review and the conclusion drawn from this, although they differ from other reviews I've read. It's good to read multiple opinions and see the reasoning and numbers behind them.

Appreciated the data driven information and stats about supplements/vitamins, breastfeeding/formula, immunizations, for both mom and baby. Not a how to book but offers good information to make your own decisions

This has been my favorite resource so far, because everything is backed by the most recent studies and is given in such an easy to understand way. I wish I had found this before pregnancy, but am so glad I found it still early enough to be incredibly helpful.

Highly recommend reading her first book before trying to conceive, and then this book at the early onset of pregnancy. If there’s any book I’d recommend for this process, it’s Rebecca’s!

Highly recommend, a must read.

As well as ‘it starts with the egg’ 4-6 months prior to TTC.

I would do almost anything Rebecca Fett recommends. Her book It Starts With the Egg changed everything for me, and I’m optimistic about the info in this book too!

This one is packed with a lot of info. It’s tough to rely on any one person’s assessment of studies, but this seems like a good book to add to the arsenal of data-related books.

So incredibly informative. I learned SO much about increasing one's odds, improving egg and sperm quality, etc. Rebecca provides an abundance of invaluable research.

A great follow up from ISWTE! I personally think this is best read while trying to conceive, leading up to a pregnancy because a lot of the info would be beneficial to know from day one.
