Crowds are gathered outside St. Mary’s hospital in London, hoping to catch their first glimpse of the newest member of the Royal family.

But they may have to wait until tomorrow.

The still-unnamed prince spent the night at St. Mary’s Hospital with his parents, the Duke and Duchess of Cambridge.

A news release from Kensington Palace says the new Prince of Cambridge will be remain in the hospital this afternoon and could be taken home either this evening or tomorrow morning.

The baby still doesn’t have a name. The royal family traditionally takes its time announcing the names of its newest members.

Meanwhile, many Canadians welcomed their future sovereign yesterday. Prime Minister Harper sent congratulations. The CN Tower, Parliament Hill, and Niagara Falls were bathed in royal blue.
