The X Factor winner uploaded a selfie to Twitter on Friday (12 September) and declared: "Feel slightly normal again today."
Sam, 37, gave birth to a baby girl on Wednesday, 10 September, but has yet to publicly reveal the tot's name. Instead, she's going by the nickname 'peanut' for now.
Earlier today, the singer told fans that husband Craig Pearson was taking over on parent duty for a while so she could enjoy some sleep after returning home from hospital.
And it was a blissful sleep!
Sam joked: "I GOT TO SLEEP ON MY FRONT!!!"
The former prison guard also posted a very sweet public message to her hubby, saying: "Love you babe. You have given me the gift of three beautiful babies and I love you more than ever."
Sam announced her third pregnancy earlier this year, shortly after triumphing on X Factor's tenth series.
She was mentored to victory by Sharon Osbourne, who is now the proud godmother to her tiny newborn daughter.
A thrilled Sharon tweeted her well wishes to Sam earlier this week, saying: "Congrats to Sam and Craig on the birth of their baby girl this am! Delighted to be her godmother – my first time. Such joyous news!"
