Chelsea Clinton celebrated the first birthday of her daughter, Charlotte, on Saturday with the sweetest photo of the two of them getting ready for lights out.

"Last book for Charlotte before bedtime on her first birthday!" the 35-year-old wrote on Twitter. "Marc & I are so grateful every day to be her parents."

It's not often that Chelsea shares photos of her daughter, so Clinton fans started gushing as soon as it was posted, with Chelsea's mom, presidential hopeful Hilary Clinton, retweeting the photo.  

Interestingly, Hilary shared a campaign video on Sunday with the caption, “You should not have to be the grandchild of a former president to know that you can make it in America.”

Charlotte is the first child for Chelsea and her husband, Marc Mezvinsky. Her first birthday landed one day before the annual Clinton Global Initiative conference, an event organized by the former first family, where global leaders help promote positive change and solutions for the country's most pressing problems.
