Breastfeeding help!!!!


Does anyone have any good advice on breastfeeding I made it 7 weeks with my now two year old and had to quit. It was devastating. I really love breastfeeding but dried up. Was put on mess tried beer and everything. She wouldn't latch properly and had lots of really sore nipps. Please if someone could help I have three months to learn about this before the next one comes. Really would appreciate some help. Thanks
