Breastfeeding mums...

We are now just past our 1 month breastfeeding mark and we still havnt fed properly in public (only because we dont spend much time out as its cold ect) but we have a family event coming up where we will be around alot of people, how did u go about breastfeeding in public for the first time? Im very nervous, is there clothing that is easier? Should i take a extra blanket? Anything else i need? Im used to having my boobs out all day as im a sahm😂 tia x
