Jessica AlbaJessica AlbaMum-to-be Jessica Alba has revealed what's been filling her slumber thoughts.

And it ain't counting sheep, but rather something of the boob nature.

She apparently told Extra she's been having dreams about babies, and um, breastfeeding.

She's quoted as saying: "(One dream) had to do with breastfeeding, which is the only thing I'm paranoid about. More than giving birth."

The actress, who announced her pregnancy in December, also admitted to being more emotional of late, saying: "Anything could make me incredibly angry or break down crying. That's not something I'm used to."

Welcome to the hormone roller coaster, love.

And what of keeping her svelte waistline?

She revealed: "I try to eat as healthy as possible... (and) exercise. As long as I don't gain too much, too fast, that's the key."
