I've been nervous to try it, but I figure the longer we wait the more I will talk myself out of trying

A good friend with three (older) daughters is watching our 3 month old while we get dinner about 10 minutes from her house. I'm a little worried about delaying a feeding (breastfeeding) but I think if we get a little off track occasionally it won't screw my supply up too much, right? She eats every 2.5/3 hours and I am hoping to not go over that time by much!

Anyone else with a recent first post-baby date or looking forward to their first soon?
