breastfeeding

Ok ladies I want to breastfeed & this will be my first time doing so..I want to attend a breastfeeding class just to get an idea of what to expect & also learn but do y'all have anything that could help me or any tips would be great!!! I have so many questions about it I bottle fed my other 3 so to me it seems a tad more to do since this is my first time...think I'm over thinking it so it seems to be harder but I know moms that have & still are breastfeeding may say different..thank y'all anything will be helpful 💗🎀
