It has been reported that Angelina is having a difficult time at home with the twins.

The Lara Croft actress is taking on her most challenging role yet, as mother to six children.

Sleep-deprived and emotional, Angelina is said to be receiving medical treatment for her stress.

A source tells Now, "She's in tears up to three times a day and so tired that Brad's found her collapsed asleep in the bath twice.

"She's been working around the clock, breast-feeding the babies and trying to get them to sleep. But as soon as one of them drops off, the other wakes up for another feed.

"She's also not eating very much right now and blames that on being busy. The doctor says that she needs more calories to gain strength and ensure that her breast milk is healthy."

The magazine also reports how the couple have hired help on hand at all times and are now looking for a nurse to stay for six weeks.

It sounds like Angelina could do with some time off...
