what are some songs about babies, or songs which feature samples of
baby noises? e.g. Newborn by Muse, One Big Mob- Red Hot Chili Peppers
features a baby crying.

Dear Stuz, 

A very comprehensive list of pop songs about babies, children,
toddlers or child bearing is available at the Baby Man's site
(http://www.babyman.net/BabySongs.htm).

Another list could be found in Amazon, in a compliation of songs on
fatherhood:  Golden Slumbers: A Father's Lullaby by Norman Brown,
Brian Culbertson, Rick Braun, and Dave Koz. (Amazon link:
http://www.amazon.com/exec/obidos/tg/detail/-/B00006785T/002-1439722-9219256?vi=glance)

To this list we could add not only Xarqi's suggestion of "Stay up
Late" by the "Talking Heads", but also their "Little Creatures", both
from an album of the same name.

A sampled baby could be found also in Neneh Cherry's "Crack Baby",
which is naturally a very melancholic rap.

Baby coos could be also heard in Aaliyah's "“Are You That Somebody”. 

Two alternative electronic artists that might be added are Bruce
Haack's twisted digital kid's record Hush Hush Little Robot ; and Ivan
Pavlov/COH, Enter Tinnitus (Rastermusic) - both sample baby voices,
laughs and cries.

Another alternative band, Snake River Conspiracy, sampled baby cries
in the song "Breed" in "Sonic Jihad".

Finally, Blue Suede's ""Hooked On A Feeling" has nothing to do with
babies, except for the fact that it would be always remembered as the
song that followed Ally McBeal's "dancing baby":

I hope this answers your question. I searched the Internet to find
these songs by using combinations such as "baby songs" "smapled baby"
etc. Please contact me if you need any clairifcations on this answer
before you rate it.

Talking Heads:Stay up late.

Kooks - David Bowie

My favorite is "Isn't She Lovely", by Stevie Wonder.

"A little ray of sunshine." Lyrics by Brian Cadd and Don Mudie
Singer Glenn Shorrock

And here's a whole CD of baby sounds!

There's a lot of little baby sounds like giggles and such in Tristan's
"Je veux une Bebe". He's a French singer (I don't know if he still
performs at all or what) and that song was out around 1988-89.

Flesh For Lulu also has a song that begins with a baby crying. It's
called Siamese Twist and it's on their Cd, Long Live the New Flesh. It
is from about 1988 or so as well.

Madonna's "Dear Jessie" has a little kid giggling in it.

Actually the sounds in 'One Big Mob' are made on a guitar, its not a
baby crying.  What you hear is the pick rubbing up and down a wound
string.
