The former Saved by the Bell star became a first-time mother in July (12) when she welcomed a baby boy, named Sky Cole, with her artist husband Greg Lauren.
Berkley has now opened up about her "magical" experience of motherhood, but admits she can't stand being separated from her little boy.
She tells Usmagazine.com, "I'm going through separation anxiety... (Motherhood has) been amazing and magical. I have a lot of friends who have little ones and I love their kids, but until you have your own, it's like you can't quite grasp the intensity of the love, the depth of it... it's so special... I'm really savouring this time.
"I have a lot of work I will be doing, but I'm just enjoying the focus of where I should be. You can't get this moment back, you know what I mean? That's why I'm savouring it."
