1st baby- nursed/pumped for 3 months, then I got sick and couldn't proceed.
2nd baby- exact same situation; apparently that's my body's way of telling me 'enough!!'
3rd baby- oh my GOD, biggest struggle EVER. My milk didn't come in right away, as it had with the first two... cried my way through formula supplementing the first 2 WEEKS.... then nursed and pumped for 6 months, until I became deathly ill (again, my body was DONE)...
Bottles are not evil. I'm a HUGE advocate for breastfeeding, but I will say, do what your mind, body, and baby are telling you. Whether you exclusively breastfeed or your new baby decides bottle is best for him/her... go with it, save your sanity. Don't lose hope, get in touch with lactation consultants and mom's who have been there... but bottles are not evil :)
Happy baby, happy mommy!! Congrats and good luck :)
