Chrissy Teigen is already teaching her daughter Luna Simone one of life’s most important lessons: when you make a mess, you have to clean it up.
On Friday, the Sports Illustrated Swimsuit model — who recently announced she was pregnant with her second child — shared a series of videos on Snapchat of her daughter cleaning up some water that got spilled on the floor.
“It’s just water,” Teigen, 31, told her 19-month-old daughter. “Can you help me?”
Bending down with a purple towel in hand, Luna followed her mother’s instructions and soaked up the excess moisture. “Thank you,” Teigen said.
Later, Teigen shared a video of her helpful daughter eating dropped food in front of the TV which she captioned: “the greatest age.”
On Tuesday, Teigen announced that she and her husband John Legend were expecting their second child.
In an adorable Instagram video, Teigen can be heard asking her daughter “Luna, what’s in here?” as her daughter pointed at her mom’s stomach and proclaimed there was a “baby” inside.
“It’s John’s,” Teigen cheekily captioned the video, to which Legend, 38, replied that “Maury will have the final word on this.”
Just a couple days before the big news, Legend told PEOPLE he and Teigen had been “working on” baby No. 2. Opening up to InStyle about her journey to motherhood via in vitro fertilization, Teigen explained she and her Grammy-winning husband started with 20 embryos and narrowed the number down to three after screenings.
Sources also told PEOPLE the superstar couple have been hoping to expand their family for quite some time.
“They have been planning for this for a long time. Chrissy is really excited to finally share the news,” an insider told PEOPLE exclusively about the stars.
“They are so excited to make Luna a big sister,” said another source. “They think Luna will do a great job with the baby and they’re really happy to be expanding their family.”
