Parents have revealed the most emotional milestone in bringing up a child is the first day at school.
Researchers who polled 2,000 parents of schoolchildren found that while parenthood is crammed full of millions of joyful moments, taking your son or daughter to school for the first time was the most memorable and emotional.
Eight out of 10 parents captured the milestone with a 'first day of school' photo of their son or daughter proudly dressed in their new school uniform - and a quarter uploaded the photo to Facebook straightaway.
Among the other emotional milestones were children's first wobbly steps, their first word and celebrating their very first birthday in the research by Sainsbury's.
