While gracing the launch of a documentary film series about mental health, "Out of the Blue," Kate Middleton talked about parenthood. But before that, as the Duchess of Cambridge, the wife of Prince William gave a heart-warming tribute to the recent Westminter attack.

"I know you would all want to join me in sending our thoughts and prayers to all those sadly affected by yesterday's terrible attack in Westminster," Kate Middelton said. "We will be thinking of all the families whose loved ones were killed or injured."

The 35-year-old delivered her speech hours after Prime Minister Theresa May advised that the best way the Britons can respond to terrorism is just to act normal, Daily Express reported. The mother of two went on to say that they were about to remember all the families as they discussed that "important issues" they were going to tackle.

Kate Middleton then opened up about her personal experiences as a mom. She revealed that being a mother was both rewarding and a great challenge, even though she has a lot of supports inside their home.

In fact, Kate Middleton explained that nothing can make a woman prepare to the overwhelming events one can experience from being a mom. Being a mother brings in multiple kinds of emotions from happiness to exhaustion, love and worry that one can experience at the same time.

According to Us Weekly, the woman's original identity can change overnight the moment they become a mother. Usually, the lady would primarily think of herself as an individual then it would suddenly alter to thinking your kid first and foremost before yourself.

To recall, Kate Middleton wedded Prince William at the Westminster Abbey in April 2011. After two years, she gave birth to Prince George (3) in July 2013 and to Princess Charlotte (1) in May 2015.
