"To say she was shocked would be an understatement," a source told OK!. "She's suffering more from exhaustion than anything else."

If that weren't enough, the Duchess is reportedly already at a high risk for pregnancy complications as she isn't eating as much as she is supposed to in order to maintain a healthy pregnancy weight.

The insider dished, "She hasn't had much of an appetite, so she's hardly gained any weight. Kate is very good at putting on a brace face, but everyone just wants to make sure she's taking care of herself."

Even with all the help she gets with her royal nannies, Kate is supposedly not looking forward to even more sleepless nights with four children under the age of 4.

"Kate was a little discouraged. She wasn't sure if she would cope. She's still in the fog of having a newborn, and the thought of months and months of more sleepless nights with two babies caused her to panic," the souece said according to the report. As for the rest of the family, "They're all so excited at the prospect of twins."
