"With a Child's Heart" is a song by the singer by the singer Stevie Wonder, from his album Up-Tight. The song was released as the b-side to the single "Nothing's Too Good for My Baby".

The song was later covered by singer Michael Jackson and released as the first single from his 1973 album Music & Me. The song peaked at #50 on the Billboard Pop Singles chart, #14 on the US R&B chart, and #23 on the US adult contemporary chart. Nearly all disc pressings of the Michael Jackson single had a track called "Morning Glow", the ninth track on the album originally written by composer Stephen Schwartz.

"With a Child's Heart" was later covered by American singer Raven-Symoné, taken from her second studio album, Undeniable. It was released as a single in 1999. Raven toured the United States going to various schools and malls to promote the single, and even went on a tour with pop group 'N Sync.

Three music videos were made for the song: the first one used the original "uptempo version", the second used the "ballad version", and the third used a remix. Despite the music videos and heavy promotion, the single never took off and failed to dent the charts.

With A Child's Heart
Go face the worries of the day
With a child's heart
Turn each problem into play
No need to worry no need to fear
Just being alive makes it all so very clear
With a child's heart
Nothing can ever get you down
With a child's heart
You've got no reason to frown
Love is as welcome
As a sunny sunny day
No grown-up thoughts
To lead our hearts astray
Take life easy, so easy nice and easy
Like a child so gay and so carefree
The whole world smiles with you
As you go your merry way
Oh with a child's heart
Nothing's gonna get me down
