Brooklyn Decker sobs uncontrollably after dropping her son Hank off at daycare

Brooklyn Decker proved she's like any other mom.

The "Grace and Frankie" star dropped off her son Hank at his first day of daycare, and she got emotional to say the least. The 30-year-old star was loudly sobbing in the car as her off-camera friends attempted to console her.

"Hank's first day of daycare was the WORST. For me. It was the worst for me," she captioned the tear-jerking video. "He was completely thrilled. He didn't even turn to say bye. 'Peace out, mom.'"

While driving, Decker is heard talking -- in between sobs and sniffles -- on speaker phone to a friend about her nearly 2-year-old son: "It's horrible. Oh my gosh, he just walked off. He was totally fine!"

To which her friend in the passenger's seat replied: "That's because you're a good mom and you made him so excited about this."

Brooklyn then tearfully added, "There was this sweet woman, she just grabbed his hand and was like, 'Okay,' and they just walked away."

Our hearts are breaking!

Decker is currently pregnant with her and husband Andy Roddick's second child, and this time the couple is expecting a baby girl. Brooklyn gave birth to little Hank in 2015, and she hasn't been shy about talking about the realities of parenthood -- both glamorous and not:

"You just have to live it and breathe it, and your kids will learn from that. That's what my mom did. She was a total badass, and I feel like that's how you learn as a kid."
