@StefR The Baby New Year is a personification of the start of the New Year commonly seen in editorial cartoons. He symbolizes the "birth" of the next year and the "passing" of the prior year; in other words, a "rebirth".

Since ushering out and in the New year is the Baby New Year's job, what does he do the rest of the year

Although, another myth associated with him is that he is a baby at the beginning of his year, but quickly ages until he is elderly (Father Time) at the end of his year.
