Eva Amurri has been documenting her recovery from breast reduction surgery, explaining that her size 32F breasts went up and down in size with each pregnancyThe mom of three shared that she's struggling with sleep and resting after the surgery, comparing her lack of sleep to the "newborn phase of motherhood" However, she said it's "worth it," saying that even when Amurri, 40, was a teen she never "had boobs that looked this good" Eva Amurri has been documenting her recovery from breast reduction surgery, sharing that sleeping — and coming to terms with giving her body time to rest — has been the hardest part of recovery. The actress 40, explained that she’d made the decision to have her 32F breasts reduced in a post on her lifestyle site, Happily Eva After, titled Bye, Bye, Boobies. As she wrote, larger breasts “can make you extremely self-conscious and insecure. They hurt your back, they’re hard to clothe, and most importantly: you can’t take them off and take a break. That’s been the hardest part.” Amurri, the only child of Susan Sarandon and Franco Amurri, continued, “Having huge boobs has been a blast at times! When I want to feel extra sultry or sexy, they’ve been super fun! In the bedroom? FANTASTIC. When I want attention? Perfection. But what about those days that I didn’t? What about when I would have done anything to not have to carry 10 extra pounds on the front of my body or have breasts I couldn’t put away or ignore?” Amurri, who shares daughter Marlowe, 10, son Major, 8, and son Mateo, 5, with her ex-husband, soccer player Kyle Martino, said that pregnancy and nursing caused her breasts to get bigger and smaller. “The yo-yo-ing size contributed to drooping and sagging.” She finally explained that she was having the reduction — celebrating with a “Bye, Bye, Boobies” cake — and shared her reluctance was due to her fears around anesthesia. She shared a loopy post-surgery video, filmed while her husband, chef Ian Hock was driving her home, where she said she was "obsessed with everyone," admitted that she had a "mental breakdown" before the procedure — and then broke into tears when she realized her surgeon, Dr. Umbareen Mahmood, gave her chocolate. Recovery has been tough, Amurri revealed, explaining she’s “so uncomfortable” and can't sleep. “The truth is that until I can sleep on my side … I just feel like I’m in the newborn phase of motherhood where I’m up pretty much constantly,” The PEOPLE Puzzler crossword is here!

"I feel a lot of guilt when I'm not doing something that can objectively be seen as productive." “I will tell you, though, that the girls are looking real good,” she said. “I don’t think I ever had boobs that looked this good, even when I was like, 18.
