Breastfeeding is hard to do. Those of us who’ve gone through it personally know exactly what we’re talking about.

If there’s one thing that bonds all mothers — whether you’re a celebrity or regular folk — it’s the breastfeeding conversation: Should I or shouldn’t I?

Hear what these celebs had to say:

Sienna Miller

“I do miss my breasts being where they were. And, yes, I have nipples like fighter pilots’ thumbs,” the actress joked to Allure. “But I also sort of like that they’re a little ’70s. And that they fed my kid.”

“I lost most of my weight from breastfeeding and I encourage women to do it,” Beyonce, who is pregnant with twins, said to People. “It’s just so good for the baby and good for yourself.”

“The feeding schedule surprised me a lot. If you kind of do the math, you’re kind of breastfeeding for 10 hours a day total,” she told Entertainment Tonight. “It’s very loving and sweet, but it’s not easy. It’s hard to work your entire day around getting her the nourishment she needs because [babies] are just little animals.”

Kristen Bell

“I was like, ‘My craft deserves it. I gotta do it. I’m a serious actor,’ ” Bell told Seth Meyers during an appearance on Late Night. “I was breastfeeding at the time. I wanted my character to have an aggressive boob job, like it’s the only thing you can think about when you see someone … so I didn’t pump for a full day. And I said to the kids, ‘Daddy’s making a movie, go to the fridge, the food truck is closed.'”

Kelly Rowland

“All that gnawing at your nipples will take its toll!” she wrote in her parenting guide, Whoa, Baby! “In those early days, I was fascinated (my polite way of saying ‘horrified’) by the transformation of the boobs. My nipples were HUGE — we are talking the size of Frisbees — and sometimes I could see these veins bulging out while I was nursing. My boobs themselves were so long and stretchy that I sometimes felt like I could’ve swung them over my shoulders.”
