it's like taking baby from a candy

I believe that "taking baby from a candy" is a much better expression than the one we are all familiar with. It implies that the act which you are referring to is extremely easy. Don't get me wrong, in my experience taking candy from a baby has always been a breeze--but sometimes their little fingers don't like to pry open and the screaming is slightly uncomfortable. The only difficulty you may have with taking a baby from candy is if the candy in question is gum, as gum (had it been previously chewed) could temporarily glue the infant to a surface.
