Stacie,
THere are so mant things to consider and I identify with your dilema. I desparately wanted to bf and for lots of reasons it was very hard. I managed 3 months, but that was with some formular.
Don't let anyone's expectations influence you, this is your decision(with support from your partner if you have one).
Just a thought, I stopped bf very slowly. I replaced one bf with a bottle
every week until there was only one bf, then I carried on that one bf for several weeks. Admittedly, that did decrease my supply but it meant I was bfing(partly) for about 8 extra weeks. if anyone asked I said, 'I breast and bottle fed' and left it at that. Lots of people wanted to know why I was giving a bottle to a small baby, but if the above answer didn't satisfy them I said 'it is because of medical reasons that I'd rather not talk about'.Which was only partly true, but they shouldn't be so nosey.
I'm not saying you should do what I did, but I wanted you to know lots of people struggle and part bf and part formular is possible.
Whatever you decide
do not let yourself feel guilty you are giving your lo all the love, food and nurture they need and they won't mind if it is bf or formular as long as their tummy is full! If nothing else your lo has had the benefit of 7 weeks of bf.
