Christina Aguilera and her fiancé, Matthew Rutler, documented a little family fun in the sun by posting home videos of their 9-month-old daughter, Summer Rain Rutler.

Moments like these are important to Aguilera. The Grammy Award-winning singer told E! News in March, "The best thing is seeing my children's smiles every day — knowing that they are happy makes me happy."

They've taken trips to the Los Angeles Zoo, helped Summer create a message in a bottle and even took a baby boating trip.

Rutler joined Instagram four weeks ago and this week, the couple shared two 15-second home videos— one on his account and the other on Aguilera's — of the family enjoying a few exciting summer excursions.

Aguilera's 7-year-old son, Max Bratman, who is from her previous marriage to Jordan Bratman, also makes a cameo in the video of the zoo that she posted to Instagram Monday.

A week ago, Rutler shared another home video that shows the new parents helping Summer write and toss into the ocean her first message in a bottle.
