New mother Evan Rachel Wood is already struggling to get back into work mode as she suffers "separation anxiety" whenever she is parted from her newborn tot. The actress 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 in New York, Wood revealed she hated leaving her baby at home while she went to work, saying, "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!' "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?" However, the star insists being a mother has turned out to be her favourite role to date, adding, "It was my dream to be a mom, so I'm loving it. I love it." The tot, whose name Wood is yet to reveal, is her first with husband Jamie Bell.
