question regarding nipple confusion

Wani

hello im a ftm not due anytime soon but getting anxious thinking about breastfeeding, i exclusively wanna breastfeed and have lots of questions about it like what is a pump for? because i keep seeing how giving your baby a bottle will confuse them and the baby won't wanna breastfeed it all just seems very confusing to me i'd really appreciate some help i hope i made sense lol
