Re: Bridesmaid while breastfeeding - am I stressing for nothing.
If you haven't already tried them, LilyPadz are amazing and would probably help you out immensely in this situation. They literally seal off your nipples so you don't leak even when you letdown. They do wear out over time and have to be replaced. If you get a pair don't overuse them before the big event.
I often pump and take bottles of breastmilk with me when I'm out and about. It's so much faster to bottle feed on the run than it is to sit down and nurse. You could go hide some place and pump quick and then come out and have someone else feed the baby too. There are lots of ways you could do this. You could pump enough in advance that you could get a sitter for the whole day and bring a cooler and pump when you feel full. You could bring someone along to nanny the baby there and pump so they can feed the baby bottles. You could even just take a break every 2 hours and hide somewhere with the baby real quick.
