Haylie Duff has shown off the first picture of her baby daughter

She captioned the picture of Ryan, who was wearing a pink bathing suit: "Baby's first vacation."

She then followed up the picture with a second image of the tot's face.

Alongside it, she wrote: "Our sweet baby girl #RyanAvaErhard Rosenberg is 16 weeks today (sic)"

'The Real Girl's Kitchen' star was recently praised for her parenting skills by her sister Hilary Duff.

She said: "She's doing great and I'm so proud of her.

"She's really a natural mom."

However, the 27-year-old star - who has three-year-old son Luca from her previous marriage to ice hockey player Mike Comrie - did admit there is one thing her big sister is not so good at, as she regularly calls her up to help wrap up the newborn baby.

She said: "I've been there a lot. I give a mean swaddle so [Haylie's] always calling me like, 'Come over here! Give this baby a swaddle'. It's really fun to have a new addition to the family."
