The "Transformers star", who initially did not want to hire anyone to help during the first few months, said she hired her because she feared their marriage would end in divorce if the sleepless nights continued, reported Contactmusic.
"Having an infant is difficult. It's a lot of work and I didn't hire any help because I overestimated my own abilities. I had no idea how difficult babies could be, so Brian and I were exhausted.
"I said to Brian, 'We have to get a night nurse or we're going to get a divorce because someone's got to sleep in this house or we're going to kill each other," she said.
The couple now has a nanny who helps with the baby two evenings a week.
