Having a baby is like living with a drug addict

London: Actress Blake Lively thinks having a baby is "like living with a drug addict".

The 27-year-old beauty, who married actor Ryan Reynolds in 2012 and gave birth to their first child James in December 2014, said living with a newborn child has posed some unusual challenges, reported Contactmusic.

"Having a baby is just living in the constant unexpected. You never know when you're gonna get crapped on or when you're gonna get a big smile or when that smile immediately turns into hysterics. It might be like living with a drug addict," she said.

"You have a baby and you think, 'I can't imagine ever not having a baby', because they grow up so quickly. I'd be an 80-year-old woman with a baby if I could," she added.
