Olivia Munn went days without sleep during baby's first illness

The 42-year-old actress welcomed her little boy Malcolm with her comedian partner John Mulaney in November and she has now opened up about her baby's first battle with a bug - admitting she was looking after him around the clock.

In a post on Instagram, she wrote: "Got through our first sickness. Haven't properly slept since last Wednesday but there's nowhere else I'd rather be than cuddling my little boy and being covered in his explosive poop."
