Danielle Fishel, former "Boy Meets World" actress, welcomed a baby boy, Adler Lawrence Karp, with producer Jensen Karp in June 2019 -- four weeks early.

Although everyone seems to be in good health now, the birth was a bit jolting, as Fishel, 39, previously revealed on Instagram.

"I was hospitalized that night and put on magnesium sulfate because Adler was only 35 weeks old," she explained at the time. "Unfortunately, after doing an ultrasound, our amazing OB discovered fluid in his lungs that was not there during our last appointment only 10 days earlier -- and thus we entered a nightmare we'll never forget."

"I never thought this day would come. When I learned I was pregnant, I started thinking about when I'd feel the first kicks. Then, when I was feeling the flutters, I wanted to know when I'd finally start to show," Darby, 31, said in an Instagram post announcing the birth.

She continued: "After watching the bump grow, my mind went to birthing day (WILL THIS REALLY HAPPEN?!) And when the day finally came that this sweet child came into our world, it felt like the sunniest day after a sky filled grey."
