The 30-year-old actress, who gave birth to Marlowe in July with fiance Tom Sturridge, says she hates being apart from her little girl, reported Contactmusic.
"My life is really different: it's much better. People told me not to have kids, but I think motherhood's got a bad rep - I don't feel compromised. In fact I don't want to be anywhere else except with her," she said.
Miller had said she finds motherhood surreal.
"It's still the most surreal thing, that you can create, that I grew this life inside my stomach, her eyeballs, everything - every little fibre. And I'd expected that she'd be this extension of me and I'd instantly understand who she was because she'd come from me, and then you realise that they are their own people entirely. Very connected to you, of course. But they're their own person," she had said.
