need a bit of advice

I am currently pregnant with my first child and I have a friend who is getting married next year. my baby will not be a year old by the time she gets married and i plan to still be breastfeeding. she has said that no children other than family will be allowed at the wedding, when I got married both of her kids was there and I really don't know what to do as I want to be there but at the same time don't want to have to be worrying about stopping breastfeeding quicker than I want to 😊
