The key concept is the fourth trimester. In other words, that babies are born four or five months before they're ready for the world.

Well, if that's the case, then how do you imitate the womb? They're not fully baked and they're ready to be out. How do you imitate the womb?

And it turns out that the womb is not a quiet still place. It is a symphony of sensations. The sound is louder than a vacuum cleaner.

This blood flow sound. Babies are rock every second. Every time you breathe, you're rocking your baby.

And of course, when you're walking around or going up and down the stairs, it's extra jiggling. And people often notice that the baby wakes up when they go to bed. The fetus starts kicking more.

But when they're walking around, it's busy that fetus is actually quieter. And then in the womb, they're also very snugly held.

And so sound, motion, and snug holding are things that parents for thousands of years have recognized, calm the babies.

Thank you, Dr. Mona. Happy to be with you.

Well, it's a pleasure. I myself as a pediatrician and mom know so much about you, obviously, about the Happiest Baby on the Block and now the Happiest Toddler on the Block.

And so when I introduced you, I said, if people don't know who you are because one of your books are one of the most popular books in the parenting space and your resources as well.

For anyone who's not familiar with who you are, if you can introduce yourself and what brought you to create these books and resources for parents abroad and around the world.

Oh, yeah, sure. Well, I'm a pediatrician like you. I train in New York and in California and then I did a few years of studying child development, which is kind of a weird idea for a lot of parents because isn't pediatric's child development.

It almost sounds redundant, but it turns out, of course, as pediatricians, we're trained to take care of very sick children and medium sick children and slightly sick children and child development sometimes gets pushed to the side.

And I kind of thought if I'm going to spend the rest of my life taking care of, you know, little kids and families, I wanted to be interesting every day.
