Babies have to do this. Kids want to do it, but adults can't.

Don't try to steal from my library because I can turn my head three hundred sixty degrees. I appreciate any contribution but if slighted you won't hear my retribution.

I occur once in a minute, twice in every moment, but not once in a hundred thousands years. What am I?

In making a word wordy, The shell of my former self has now become A dog of the snow, with gruff voice.

Pronounced with one letter, but written with three, The letter that is, is similar to me. I rest in the center of winds, calm as ever, I'm easy to close, it's like flicking a lever. I come in many shades and hues, Of browns and greens and greys and blues.
