Issues with family while 7months pregnant

Hi is anyone else being tested while pregnant by family? Like your family causing drama in your relationship because I need advice on how I should handle it. My mom has been saying negative things about my bf/ baby father and he saw what she said and reacted to her comments by posting on social media how he feels because he is tired of the fake nonsense. My little sister txt me telling me I need to check him and blah blah.... how would you handle the family?
