In an Instagram post on Monday, Emma shared a picture of daughter Mabel holding sister Evelyn (presumably), as she encouraged mothers to 'start to journal' and capture their children's special moments.

The couple, who married in 2009, have two children between them. Meanwhile, Bruce has Rumer, 27, Scout, 24, and Tallulah, 21, with ex-wife Demi Moore.

In an Instagram post on Monday, Emma shared a picture of daughter Mabel holding sister Evelyn (presumably), as she encouraged mothers to 'start to journal' and capture their children's special moments.

'You never think you will forget those precious perfect memories of your children’s childhood…Until you do, My advice: Start to journal. I’m giving you the full scoop over on my site today. (link in profile) #Mommylife #family,' she stressed.

On her website, EmmaHemmingWillis.com, the 5ft 10in beauty, who previously kept a baby book, revealed the moment she realized she needed to write things down, having admittedly slacked off.

'I recorded everything until one day, I just stopped. I would say to myself, there’s no way I’ll ever forget this moment. It’s ok if I don’t write it down because I’ll etch it in my memory forever! Well… I forgot the moment. Couldn’t even tell you what it was or when it happened,' she confessed.

She pledged to begin to document their firsts and listed several notebook and journal options to do so.
