Breastfeeding...

Ill be 36 weeks Monday and doc wants to induce between 38-39 weeks. Hoping he will come on his own. But I'm starting to get very nervous/anxious about the whole process or breastfeeding. This is my third pregnancy, my first two were bottle fed. This time around my heart is set on breastfeeding. The more I educate myself the more scary it becomes 😕... Can some of you ladies that have mastered breastfeeding share some tips and encouragement? I just recently started reading about cluster-feedings and I'm terrified lol. If I'm feeding and pumping when will I ever sleep? When should I introduce baby to expressed milk?
