It's been a big week for Holly. On Monday, her youngest child Chester, four, started school for the very first time. The This Morning star, 38, shared a photo with her fans, showing her doing the school drop-off with her little boy. "And he's off... full of a whole host of emotions watching him walk through the classroom door... my baby is growing up... thank you @thismorning for moving heaven and earth so I could drop him off... that's a day we will both never forget," the mother-of-three wrote.

The bittersweet post comes after Holly shared a photo of her children's shoes lined up by the front door on Sunday night. "Back to school... who else's front door looks like this... Big day for Chester tomorrow, 1st day of school... Good luck to anyone else starting their school journey... can't believe he's at this stage already," Holly told her fans. Luckily for Chester, the new schoolboy was joined by his older siblings Harry, ten, and eight-year-old Belle, who no doubt looked out for him on his first day.
