With no nanny or night nurse, Mila Kunis is having a rough go at motherhood, insiders close to the actress share with Life & Style.

“Mila has spent a lot of time in bed,” one source reveals. “She’s obsessing about her daughter’s health and feels like she’s fat and will never lose the weight.”

She is so miserable, that one source speculates she may even have postpartum depression.

“Getting the baby blues is common, but if it lasts more than two weeks, that could be postpartum depression,” ob-gyn Dr. Draion Burch tells Life & Style.

Fiancé Ashton Kutcher is doing everything in his power to help: “He tells her she looks great, and he tries not to leave Mila alone for any length of time,” says an insider. “And he’s there to take Wyatt whenever she’s feeling overwhelmed.”
