New mom P!nk is struggling to come up with catchy material for her next album because she has lullabies on the brain.
 
The hitmaker and her husband Carey Hart became first-time parents to five-month-old daughter Willow earlier this year, and Pink loves to make up songs to serenade the tot.
 
But the baby tunes have done nothing to boost her creativity as she attempts to create punchy new tunes for her forthcoming project.

She tells Eonline.com, "She stops crying when I sing. I sing 'You Are My Sunshine,' and I make up songs for her because I'm goofy."
 
And Pink fears her next album won't pack a punch if she can't escape her nursery state of mind: "I promised my fans I wouldn't write an album full of lullabies."
