Gisele Bundchen shares adorable photo of her kids' 'measurement day'

Gisele Bundchen recently shared a heartwarming photo that many moms can probably relate to.

The supermodel, who has two biological children with New England Patriots quarterback Tom Brady, Benjamin, 9, and Vivian Lake, 6, and is stepmother to his son from his previous relationship, John Edward Thomas Moynahan, 12, posted a snap of the kids' "measurement day."

In the sweet photo, Benjamin is pictured measuring his younger sister's height.

"Please, tell me how am I supposed to handle this? They just melt my heart. #measurementday," Bundchen captioned the photo.

In an interview with "Good Morning America" anchor Robin Roberts last year, the world-famous model said that she "always wanted to be a mom" and "have a family."

"When I became a mother, it really became my priority," she shared. "I just wanted to be with my kids ... I couldn't ... see anything more important than being there for them ... and to be there for my husband too."

Bundchen also described her children's impact on her life in an Instagram post in May. "My kids have expanded my heart in so many ways," she detailed. "They have given my life new meaning."

"Thru them, I got to experience the deepest and purest love," she wrote. "Everyday I learn so much with them and they inspire me to be the best that I can be."

"They are truly the most precious gifts!" she added. "I am so grateful they chose me to be their mummy."
