born with a silver spoon in (one's) mouth

Born into a wealthy family. We may both be wealthy now, but I was not born with a silver spoon in my mouth. I had nothing when I was young, and all of my fortune is down to my own hard work. Everyone who attends that university was born with a silver spoon in their mouth, so I just don't think it's the right place for me. I wasn't born with a silver spoon in my mouth, and I think that really gave me a drive to succeed in life.

born with a silver spoon in his or her mouth

Financial and social advantages from family connections. It was traditional when a child was christened for the godparents to give a silver spoon as a gift or as soon afterwards as they could afford one (if they ever could). However, a child born into a wealthy family always received one at the ceremony. Such infants so privileged were said, often enviously, to have been “born with a silver spoon in their mouth,” and the image followed them throughout their lives.
