First-time mum Danielle, who welcomed Alena with husband Kevin earlier this week, has now returned home with their baby daughter.
In a photo posted to Instagram last night (5 February), Alena Rose is captured sleeping peacefully while dressed in a pink baby suit.
Captioning the photo, Danielle said: "So excited to have her home. I can't believe Kevin and I have a family #soinlove."
She later added: "This is what I waited to see for nine months. Love these two more then words can tell #AlenaRose #proudmommy."
Proud parents Kevin and Danielle have been gushing over Alena since her arrival and have shared several touching photos of their new family.
Kevin appeared to be overwhelmed as he uploaded a photo of Danielle laying across the sofa with Alena sleeping in her arms. The new dad said: "All my girls #soblessed."
In another adorable black and white photo Kevin is kissing Alena, who is wrapped up warm in a white blanket. He wrote: "It's still blows me away this is my life!"
And now that Alena's home, the whole family can get to meet the newborn.
Kevin's brother, Nick tweeted last night (5 February): "I get to meet my niece Alena Rose tomorrow.. I'm so excited @kevinjonas @daniellejonas."
And this morning (6 February), their brother Joe looked like a proud uncle as he held Alena in his arms for the very first time.
Captioning the photo, Joe said: "Welcome to this world Alena Jonas. #littlebaby #shessosmall #woah."
Kevin and Danielle announced that they were expecting a baby girl following a scan in August. Speaking at the time, Danielle said: "It's a girl !!! I am so happy I been able to share everything & not have secrets it's been so nice.
"Thank u for all the tweets of excitement... A girl. It feels so real!"
