The 38-year-old actress and her husband, David Bugliari, welcomed their first-born last week, and taking to Twitter to explain his name, she said, 'Milo was named after his two grandfathers, Miller and Thomas. Two very important men in my life.'
And she added that she is enjoying every part of being a mum – even the nappy changes.
'Breastfeeding. Poop. And bliss. I love being Milo's mother!' she said. 'Thank you for all the well wishes for my son Milo. My heart has tripled in size. I love him more than all the leaves on all the trees.'
