Please don't let anyone make you feel guilty. It's such a personal decision. My little guy would fall asleep on the boob from day 1. He didn't do his "job" when he was latched, so in return I couldn't do mine and my milk supply wasn't increasing. Then trying to pump 6 times a day wasn't realistic, my hands weren't that free. I never made more than an ounce of BM. Now he's on formula and so much haplpier, he still falls asleep on the bottle :)
I planned to BF for 3 months, but ended up stopping after the first month, however much BM you give your baby is better than none at all. You have to do what's right for you and baby.
(PS: I was a FF baby from 6 weeks on and turned out just fine - healthy, hardly ever sick and in all honors classes in school...just saying lol! Hope that helps!)
