We’re already midway through 2018 and to celebrate the half-year mark a pregnancy and parenting website has revealed the most popular baby names of the year so far.

A useful guide for parents-to-be who want to avoid giving their offspring a name that’s going to dominate nursery registers everywhere, Babycentre has released its roundup of the trendiest monikers.

Topping the girl’s chart, Olivia has kept hold of the coveted number one spot for the fourth year running, followed by Sophia, Amelia, Lily, Emily, Ava, Isla, Aria, Mia and Isabella.

Meanwhile, Muhammed remains at the top for boys, with Oliver, Noah, George, Harry, Leo, Charlie, Jack, Freddie and Alfie also making it into the top 10.

Outside of the top slots though, Babycentre has also reported a number of growing baby name trends including weird and wonderful spellings.

The website’s registration shows that Jaxon is now a more popular choice than Jackson, while Aaron has no less than 13 different spellings and Aria has 12.

Royal names have also seen a surge in popularity with Victoria, Charlotte, George and Arthur all climbing the rankings.

However, there has been no significant change for Meghan, Megan or Louis just yet, but this could all change in the full-year results.

One of the biggest news stories of 2018, the #MeToo movement has also had a significant impact on baby names this year with the Weinstein scandal instigating a drop of more than 30 per cent for the name Harvey.

Meanwhile, names of key women involved in the movement have featured more heavily in Babycentre’s registrations including Alyssa, Ashley, Rose, Gwyneth, Jennifer and Asia.
