Guest blogger Ronda Kaysen: The first day at a new school is never easy, especially if you're the daughter of the next President.

Sasha, 7, and Malia, 10, arrived at the tony Sidwell Friends this morning for their first day of school. Traveling in a Secret Service-escorted motorcade, they were welcomed by a crowd of eager onlookers and camera crews hoping to get a peek at the new First Kids. No one got so much as a wave.

Papa Barack saw his daughters off at their Hay-Adams Hotel room just after 7 AM and then the girls drove to school with their mom, Michelle. Malia got dropped off first at the middle school (a full half hour early). Sasha, a second grader, arrived at the neighboring Sidwell elementary a few minutes later. Michelle didn't spend much time settling the girls in. She was gone within 10 minutes. Sasha, usually the more outgoing sister, "wore a look of wariness and fascination as she eyed the row of television and still cameras filming the motorcade," said the Washington Post.

What will it be like inside the halls of Sidwell? Pretty low key, according to insiders. Sidwell kids are used to rubbing elbows with the children of the rich and famous (many of them are just that). Both Chelsea Clinton and Nancy Reagan are alums. By lunchtime, the newest classmates will be old news.

"In every grade at Sidwell, you have the children of diplomats and of wealthy parents, but you really don't notice a difference," former Sidwell student Delaney Kempner told CBS News.

If anyone gives the girls a hard time, though, they've already got a few allies in the classroom. Vice President-elect Joe Biden's grandkids go to Sidwell too.
