Bouncing back! Naya Rivera gave birth to a baby boy in September 2015, but you almost wouldn't know it by looking at her body.

The former "Glee" actress said she's close to her pre-baby weight.

"2016 is off to a great start already! 4 lbs away from my goal weight," the new mom said on Twitter, just four months after welcoming son Josey with husband Ryan Dorsey.

Along with getting her body back, Naya seems to getting the hang of this whole motherhood thing, too. The actress often uses Instagram to document her son's life to her 1.5 million followers.

"Seeing Josey for the first time literally took my breath away. Really, I gasped! It was such a surreal moment to be face to face with my son," she wrote while blogging for People magazine.

Before Christmas, she posted a snap of her smiling son with Santa Claus.

Merry Christmas Eve! His smile, joy, and life make everyday feel like a holiday.

She recently told People magazine that motherhood is "absolutely amazing."

"It's just something clicks," she said, "and you do it really, really well and you're instantly in love with this little person you just met, but it's awesome."
