The post resurfaced as a baby name expert revealed three things you must do before naming a child. ‌The woman explained that it's a tradition in her Irish husband's family to name the firstborn son Oisín - a name she "loves". ‌However, she was surprised when her sister-in-law, who fell pregnant just two months before her, also chose the name Oisín for her son. Despite knowing this would mean her son would share the same name as his cousin, she and her husband decided to continue with the tradition and named their son Oisín. Anyways my husband's family thinks the whole thing is hilarious, my family thinks my sister in-law is a weirdo and she thinks I'm an a*****e for copying her."
