Whooping cough vaccine

Sami • 24yrs old lost my baby when I was 9weeks, God has blessed me with a baby boy! Due June 11th!
So I talked to my family about getting the whooping coughing vaccine for when my son gets here, and they agreed to get it without hesitation. Now I had my boyfriend tell his mom so she can get hers and his little brother, she only speaks Spanish and I'm not Hispanic but I understand a little and when he told her about getting it done before my son is born she laughed hysterically and said in Spanish "I'm not" I am so pissed that she did that and said no! Anyone else have to deal with families lack of respect of your choices for your children?
