We have watched as Duchess Kate's two children, Prince George and Princess Charlotte, have grown from beautiful babies to adorable, well-behaved children.
But even the Duchess of Cambridge has admitted that motherhood isn't always easy. In honour of Mother's Day, click through our gallery to read our favourite quotes from Kate about motherhood and about her little Prince and Princess...
Kate paid a visit to the EACH hospice in Quidenham, Norfolk, this year, and mum Michala Benton said: “Kate also said about her kids that Charlotte and George run in different directions all the time.”
Chatting to the pupils at Mitchell Brook Primary School in north west London in February, the royal said: "My parents taught me about the importance of qualities like kindness, respect, and honesty, and I realise how central values like these have been to me throughout my life. That is why William and I want to teach our little children, George and Charlotte just how important these things are as they grow up. In my view it is just as important as excelling at maths or sport."
Referring back to her own childhood, the Duchess said: "When I was growing up I was very lucky. My family was the most important thing to me. They provided me with somewhere safe to grow and learn, and I know I was fortunate not to have been confronted by serious adversity at a young age."
To the mother of a sick baby at Ronald McDonald House Evelina in February, Kate said: "Having a baby is a life-changing moment but for you having to go through all that as well is extraordinary."
Kate spoke about her two young childrens' friendship at a Iraq-Afghanistan memorial service in March. Attendee Samantha Burge told reporters: "Kate said that Charlotte is growing up really fast. She is the one in charge. We have both got two-year-olds and they are ruling the roost. It was a bit a mummy chat." She also revealed that Kate said George and Charlotte are becoming "very good friends".
On a Place2Be engagement, November 2015, she said: "I know that I was lucky. My parents and teachers provided me with a wonderful and secure childhood where I always knew I was loved, valued and listened to."
Speaking about Prince George and Princess Charlotte at the Natural History Museum, November 2016, Kate admitted: "George loves the T Rex because it's the noisiest and the scariest." One of the students at the museum, Amani, 10, said: "We asked her about her home lifestyle and her children. She said that Charlotte is very chatty and likes doing play dates with George. George is interested in dinosaurs and volcanoes."
"Parenting is tough," Kate said while attending an event at the Anna Freud Centre's Early Years Parenting Unit in January. And with the history and all the things and the experiences you've all witnessed, to do that on top of your own anxieties, and the lack of support you also received as mothers...I find it extraordinary how you've managed actually. So really well done."
Proud Prince William has previously said he is "lucky" to have Kate, describing her as "an amazing mother and a fantastic wife".
Speaking about her work with mentall illness, Kate commented: "People often ask me why I am so interested in the mental health of children and young people. The answer is quite simple - it is because I think that every child should have the best possible start in life."
