Public breastfeeding?

Monica • One happy mamma! 😍 💙👶🏼
How comfortable are you breastfeeding out in public? I BF and formula but when I'm out I just feel nervous about breast feeding. At the moment I don't have a cover I'll be getting one soon but still nervous about it. My soon is 9 weeks old and every time we go out he wants to nurse, I think it's for comfort. How do you feel? Do you just not care? Every time I see women doing it I just don't understand why I care.
