Chrissy Teigen seems to have her hands full as she raises her two kids.

The mom-of-two posted a video on Instagram revealing her daughter's act.

Her daughter, Luna, appeared to be applying soap on the handle of her room door.

The curious mom proceeded to ask the six-year-old what she was doing.

Luna disclosed that she was trying to prevent her brother from gaining access to her room.

The model also showed her fans a drawing Luna made of her little brother, Miles.

The drawing which was attached to her door was to prevent the preschooler from entering.

The expectant mom and her husband, John Legend, intend to have more babies.

Legend once confessed he was selfish when he and Teigen began dating.
