Even the most sensible of adults will admit to sometimes getting competitive with their siblings at Christmas. This might manifest itself in countless dog-eat-dog games of Monopoly, or in the annual unspoken contest to get your hard-to-please dad the best gift. Or sometimes it might surface in the form of resentment after one sibling gets more presents than the others.

And according to the results of a new survey, there’s one sibling who we expect to be more spoilt than any of the others at Christmas: the youngest girl.

Reassuringly, that doesn’t necessarily mean that your little sister is guaranteed to receive more gifts than you on 25 December. In the poll of 1,000 Brits conducted by shopping and fundraising site Give as You Live, the majority of people (76%) said they believed that all their siblings were indulged equally at Christmas.

However, one in ten people thought that the youngest sister gets the most gifts under the tree. That number jumped significantly to one in four (24%) young people aged 18-24, who were the most likely to say that the youngest girls received preferential treatment.

This is the sibling who will be most spoilt this Christmas
