Mayim Bialik told us all about her new book, her first period, and life on the set of “Blossom”

Whether you grew up with her (and loved her!) as the titular character on the hit ’90s show Blossom, or look up to her now as late-blooming genius Dr. Amy Farrah Fowler on The Big Bang Theory, Mayim Bialik has probably influenced your life. Now, Bialik has released a new book for girls, titled Girling Up: How to Be Strong, Smart, and Spectacular — out today — that tackles everything from puberty, to sex, to life after high school in a straightforward, comprehensive, and age-appropriate way. And honestly? It’s the book we wish we’d had on our bedside tables growing up.

Written in what Bialik — who is a neuroscientist, in addition to being an accomplished actress and founder of, NBD — describes as an “academic” style, the book speaks to girls where they are: confronting major changes, and possibly feeling a little (or a lot) overwhelmed. We were lucky enough to chat with the PhD and mom of two boys about why she wrote this book, her own experience as a late bloomer, and her biggest crush on the set of Blossom.

HelloGiggles: Why was it important for you to write this book?

Mayim Bialik: There are a lot of reasons: I was approached to write this book by an editor at Penguin because she read an article that I wrote about modesty, and being a late bloomer and playing one on TV. But ultimately I wrote it because I think there’s information in it that was missing when I was a kid and that girls deserve to have, especially in the 21st century when things are very different than they were when I was growing up.
