Cate Blanchett and Andrew Upton's baby daughter is a ''pleasure and a joy''.

The Australian couple adopted little Edith earlier this year and she is fitting well into their family, which also includes sons Dashiell, 13, Roman, 10, and six-year-old Ignatius.

He told Daily Mail Australia: ''The boys love her and I love her and Cate loves her and hopefully she loves us.''

Asked if she was a daddy's girl, the 49-year-old playwright laughed and said: ''She's little.''

Though Andrew initially said he doesn't want Edith to pursue a showbusiness career, he added he wanted her to ''follow her heart''.

Andrew's stint as artistic director of Sydney Theatre Company will come to an end soon, so the family will be relocating elsewhere, though he and his 'Notes on a Scandal' star wife are currently unsure where they will move to.

Andrew said: ''We're not sure about the US. We're not sure where we will go yet. We've got about a year in our minds where we will explore some of those overseas options.''

Cate, 46, recently admitted she is feeling ''sleep deprived'' from looking after Edith.

She said: ''I feel a bit sleep deprived.''

However, Cate - who is preparing to tread the boards in an upcoming production of 'The Present' - admitted there are some benefits.

She added: ''Although sometimes, it can be good to be a bit tired in a rehearsal room because your guard is down.''
