Blake Lively says she's always been a mother.

The former 'Gossip Girl' star, who is expecting her first child with husband Ryan Reynolds, isn't worried about adapting to motherhood, as she has a lot of experience with babies.

The 26-year-old actress told E! News: ''I came from a big family...a big family of Southerners. I feel like I've always sorta...I'm the youngest of five, so I never raised any siblings below me, but I'm always the person who's taking everyone else's kid and putting them on my hip, so I've kinda always been a mama. So we'll see.''

The blonde beauty also told PEOPLE.com that she hasn't ditched her healthy diet since discovering she is pregnant.

Asked about her cravings, she said: ''I haven't had [any].''

But Blake plans to stock up on ''stretchier'' clothing.

She said: ''I'm gonna amp up my style by wearing things that are stretchier. Because that's all that fits!''

The 'Savages' star admitted earlier this year that she and Ryan want a ''litter of kids.''

She said: ''I gotta get started. If I could spit out a litter of kids, I would.''
