I'm one of the ones who tried to bf but couldn't (huge DS, voracious eater, tore nipples to shreds) and went to ff within 2 days.
I have never found it a faff. Babies are happy drinking cold milk, so no need to warm it up (I'd take a bottle out of the fridge 1 hour before I thought DS was going to need it so it wasn't too cold).
DS was born 3 months after DSIL's DD who is exclusively bf. We've never spoken about the whys and wherefores; however, her DP and her MIL have both made comments along the 'breast is best' line when I've been in earshot and I had to tell them to 'mind their own business'. If a stranger makes a comment like that, or 'I wouldn't ff MY DC' etc, I just say 'woopie-doo', quite frankly! (people annoy me!).
Bf/ff is just the first of many 'oh, you're doing X, are you?' comments you will get until DC are 18 years old! Too many baby classes/no baby classes, nap in the cot/on you, sleep outside in the garden/don't go for a walk it's too cold... blah blah blah.
Make a mental note of the particularly outrageous comments you hear and post them on MN as someone did a few weeks back - it was a hilarious thread!
Congratulations, by the way
