Quick stupid question...

I know this is going to sound like a stupid question but I just can't figure it out:

What does 'LO' stand for???

I've been reading it on here for months but I finally feel the need to know. I know its regarding our babies but exactly what does it stand for. Also what does 'BF' stand for?

Sorry I'm a bit slow and not down with the lingo yet lol
