Olympic swimmer and former I'm A Celebrity... Get Me Out Of Here! star Rebecca told fans she was enjoying a lovely Sunday afternoon.
Sharing a photo of the trio, Rebecca said: "What Sundays are all about #family #love @harryneeds."
Little Summer looked absolutely adorable as she stared into the distance while being held up by her mum.
The photos didn't stop there for the happy family, as Harry also shared a picture with fans, showing him laying alongside his baby daughter.
Captioning the snap, he said: "A Sunday well spent brings a week of content #summerloving #familyday."
Rebecca and Harry welcomed Summer last month (8 June), and the first-time parents were overjoyed with their new arrival.
Announcing her birth at the time, Rebecca said she was "over the moon" and "so in love" with her baby girl. Meanwhile, Harry said it was the "proudest day of my life", adding: "I don't know how many times they can bring a grown man to tears in one day."
