Twin Adelaide sisters who gave birth to two girls just hours apart say they got to share one of the greatest moments of their lives together.

Marie Leicester and Katelyn Gil gave birth to Ariella and Elliana just a day apart at the Women’s and Children’s Hospital.

“It was amazing, it was very sᴜʀʀᴇᴀʟ and such an exciting and beautiful experience,” Katelyn said.

Both babies weighed the same and ᴍᴇᴀsᴜʀᴇᴅ the same height.

Marie’s partner Hardy Leicester and Katelyn’s partner Luke Gil were ᴇʟᴀᴛᴇᴅ and couldn’t wait to welcome the special additions to their families.

The mothers said they didn’t think it would be possible to have children because they both have a ᴍᴇᴅɪᴄᴀʟ ᴄᴏɴᴅɪᴛɪᴏɴ called ᴘᴏʟʏᴄʏsᴛɪᴄ ᴏᴠᴀʀɪᴀɴ sʏɴᴅʀᴏᴍᴇ.

“It was not something that you could ever plan. This was just a miracle I’d say and it’s such a beautiful experience to do it with your sister,” Marie said.

“I’m still trying to believe that it has actually happened and that she’s here in our arms and that special moment of being a mother and an aunty at the same time.”

Marie and Katelyn said their families first thought it was a ᴊᴏᴋᴇ when they revealed they were both pregnant at the same time.

“It was amazing, it was so fun … everyone was in sʜᴏᴄᴋ and thought it was a ᴘʀᴀɴᴋ and didn’t believe us,” Katelyn said.

Both mothers said they experienced similar pregnancies and sᴜꜰꜰᴇʀᴇᴅ from ʜᴇᴀʀᴛʙᴜʀɴ, ꜰᴇᴇᴛ ɪᴛᴄʜɪɴᴇss and sᴡᴇʟʟɪɴɢ of the ʜᴀɴᴅs and ꜰᴇᴇᴛ at similar times.
