Telling daddy....

Found out I’m having our 3rd child last Thursday. I haven’t told my husband, my first appointment is this coming Thursday and I should get an ultrasound. I am having a hard time thinking of ways to tell my husband. I’m terrified he’ll be mad. I guess I’m not really sure how many kids he wants. I know I’ve told him I wouldn’t mind 3-4 but he never said for him.
