Robbie Williams and wife Ayda Field in tears over their children's big day

Robbie Williams' children looked so sweet!

Ayda Field melted hearts on Monday when she shared a series of rare photos of her three children, Charlie, Teddy and Coco, as they headed back to school.

Robbie Williams' wife gave an insight into how they were feeling about the momentous occasion, and it seems as if the famous couple were very emotional.

It seems that Robbie Williams' daughter was feeling a little more confident, as Ayda wrote: "Teddy was excited to see her friends (but also a little nervous too : ) #backtoschool."

Ayda also shared a sweet video of their youngest daughter, Coco, as she got ready for her very first day.

In the clip, the mother-of-four could be seen getting Coco ready for the big day, helping her with her uniform and brushing her hair, while Robbie looked on fondly.

Later on, Robbie and Ayda could be seen pouting sadly at the camera and pointing at Coco's empty car seat, most likely after the emotional school run.

Ayda captioned the video: "Coco's very first day at school. Coco is happy. Mommy is sad. Daddy's gone back to sleep. It's official my Baby Baluga isn’t such a Baby anymore... #firstdayofschool #emotional #parenthood."

The couple are doting parents to four children, and their youngest, Beau, is yet to start school, although we bet he will be excited to join his older siblings soon!
