Hilary Duff feels very ''lucky'' because her son is so ''peaceful''.

The former 'Lizzie Maguire' star welcomed baby Luca Cruz into the world last month and she is enjoying parenthood very much, particularly because her husband MIKE COMRIE is so supportive.

She tweeted: ''we are all so great! Enjoying every moment of this adventure!Lucky to have a peaceful baby and helpful man!! ;) (sic)''

The 24-year-old beauty is even finding the time to shop for new clothes while Luca sleeps.

She tweeted: ''Luca taking a nap = mommy doing some damage on @NETAPORTER dammit why do I love shiny things!! ;) (sic)''

Hilary recently admitted it was a ''wonderful surprise'' when Luca was born and she realised the depth of her feelings for him.

She said: ''The list goes on and on. I felt my heart grew the second I met him. You feel so protective right away. You feel loving and nurturing right away. Everybody always talks about it, about how you don't know love until you meet your baby, and you really feel that. There are no words. It was a really wonderful surprise.''
