Once you've got the hang of it, you really will suprise yourself at how easy it can be (I know this isn't the case for everyone)
I once fedd dd2 in front of most of the relatives on my Mum's side (big family party). My Aunt was sitting next to me at the time and asked the old Classic "Are you feeding her yourself or using formula?" She hadn't even noticed I had a boob out
There is loads of useful info on MN about BF if you search the archives, though some of the current threads are a bit off-putting
Congratulations, btw
