The 26-year-old took a four-month break from filming to spend the early days of her son's life at home, but she recently returned to the promotional trail to support her new movie "Charlie Countryman".
At a screening of the film here, Wood said she hates to leave her baby at home when she has work, reports contactmusic.com.
"I was lucky because I had done three films and got pregnant so I was like, 'I've got stuff in the can. I'm taking a break," she said.
"I've been having separation anxiety because I'm so used to him being right here all the time. They kind of become a part of you, you know," she added.
The child, whose name Wood is yet to reveal, is her first with husband Jamie Bell.
