baby refuses to breastfeed again.

holly
I breastfed my baby and gave breastmilk bottles ( no formula ) until baby was 3.5 months. I became sick and was hospitalized so we went to formula to supplement, which turned into me stopping breastfeeding all together and pumping and dumping for 3 weeks while taking Medicines not recommended for breastfeeding. So I'm able to breast feed again, despite my milk being almost gone ( devestating ) but I am trying hard to continue. However my daughter refuses REFUSES the breast screams thrashes and will not latch. I understand she may have forgot but she gets so aggravated when I even try, I do not want to loose my milk supply, any suggestions.... ? I could def be pumping more but I was really hopeful on breast feeding primarily again. ( she will drink it and loves it over formula when in a bottle )
