Haylie Duff doesn't miss the life she had before she became a mother.

The 30-year-old actress - the older sister of former Disney star Hilary Duff - is surprised by how much fulfilment her four-month-old daughter Ryan, her child with fiancé Matt Rosenberg, has brought to her life.

Speaking to E! News, she said: ''There was part of me, even when I was pregnant, that was like, 'Gosh it would be nice to go to Vegas for the weekend,' or kind of do the things I normally did before I came a mother. I think that's probably the biggest surprise is I feel such fulfilment with my family and with my child, I don't miss that 'old life' stuff.''

The blonde beauty and her beau - who got engaged in 2014 - have been so wrapped up with their precious bundle of joy that they haven't been on a date since they became parents.

But it's hardly surprising the couple don't want to leave little Ryan as she's changing and growing every day and they're scared they'll miss the tiny tot hitting a milestone.

Haylie said with a smile: ''She's growing so fast, she just started rolling over for the first time.''
