The Loose Women star, 33, and husband Joe Swash, 41, welcomed their daughter Belle into the world in February.
Stacey has loved sharing how her life is now that she has become a mum-of-five.
The TV favourite took to her Instagram story to share a photo of herself cradling her five-week-old daughter as she got ready to try and get some shut-eye.
Stacey, who was dressed in cute grey PJs, smiled at the camera with her baby girl stretched out in her arms.
She told fans: “I managed to express four ounces through today.
“So me and Belle are having an early night and daddy is taking over the 2am feed and hopefully we feed again at 5/6.
“Honestly, I can’t function at the moment [cyring laughing emoji].
Stacey added: “So I’m excited to hopefully not feel like a zombie tomorrow. Happy Sunday everyone. Lots of love from us.”
It comes after Stacey admitted that she feels “absolutely f***ed” a month after giving birth.
She took to Instagram to reassure her fans that all the new mums in the world are not alone.
She shared a message from one of her followers which said: “My little princess is six weeks today and I am soaking it up as it’s going too fast, you seem to always have your s*** together even doing it alone how?”
Speaking to her 5.6m followers, Stacey said: “Public service announcement for anyone who has ever felt like ‘oh my gosh, it looks like they’ve got their s*** together and I really haven’t’.
“Please don’t feel like that. You’re doing an incredible job.
“I know it looks like I’ve just gone straight back to normal as if I never gave birth, it feels like that if I’m honest, but it’s only because of the whole sleep when she sleeps, make sure you take time to rest and recover, don’t do anything too quickly, goes all out the window when you’ve got a one-year-old!
“So I just want you to know, don’t underestimate the fact that it’s incredible this age gap, three, one and zero, I’m so grateful to have three young babies that can grow up together.
“I can assure you, 100 per cent of the time I feel absolutely f***ed. You’re not alone. ”
Stacey shares baby Belle, one-year-old Rose and Rex, three, with Joe, who she tied the knot with last year.
She is also mum to Leighton, 10, and Zachary, 14, who are from previous relationships, while Joe is also dad to Harry, 15.
