Advice??

So, october 11th i go for another check up with my doctor, and im also taking a breastfeeding class, has anyone took a breastfeeding class and does it help alot? the person is a lactation consultant & a social worker shes really nice and she does one on one! This will be my first breastfeeding class, bc with my daughter, i never took one plus after i had her she would take to breast milk so with this baby i definatly want to breastfeed! I guess my question is, have you took a breastfeeding class? And if so, how was it and your experience?
