LOS ANGELES - AUG 10:  Katherine Heigl at the CBS, CW, ShowtimeKatherine Heigl has enjoyed being a mother to her daughters, Naleigh, 8, and Adalaide, 4, and has now added a little boy, Joshua Jr., to their fold.  Despite her joy, she has gained some insights about pregnancy and childbirth.

Surprise Pregnancy

Heigl has been open about the fact that her pregnancy took her by surprise after choosing to adopt her first two children. While she says that she enjoyed the experience, she also believes that, had it not been an accident, she would never have tried to become pregnant.

She explained: “I’ve never been determined to experience pregnancy but I’m so grateful that I did. I think that if it hadn’t been a surprise, I’m not sure I would have done it. It was an incredible experience, it was kind of magical.”

Although, she has some chronic health issues and expected her pregnancy to be difficult, she describes it all as a “pretty easy experience” despite, what she described, as incessant burping and indigestion.

She also had to have a caesarean section due to her son being breech but explained that, while it was “nerve-wracking,” it “was all done in about an hour … It was way easier than I expected.”

She’s fortunate since it is often a very difficult process for new mothers.

Emotional Rollercoaster

Heigl may have been pleasantly surprised by the physical aspects of pregnancy and birth but she has discovered that the hormonal changes that women experience can be challenging to navigate.

She explained: “One minute you’re weirdly obsessed with this baby, like ‘Don’t take him out of my sight,’ and the next you’re kind of blue, you’re a little sad and a little freaked out. I actually prefer the adoption way because I wasn’t subject to hormones.”

The actress also makes it clear that the hormones represent the “only difference” she had in welcoming her children. “The moment you hold your child, you’re wholly in love and you’ll do anything to protect them and shelter them.”

Again, it’s wonderful that Heigl feels this way but some women do struggle with feeling attached to their babies in those early days. While some assume they will instantly be in love with this new human being, many discover that developing that relationship takes time – and that’s okay too.

Congratulations to their entire family on the new addition! May the years ahead be filled with love and laughter!
