breastfeeding while pregnant

Ashley • 20. Mother to the sweetest little girl ❤
I have a 6 1/2 month old and just found out I'm pregnant. Everyone under the sun is telling me I need to quit breastfeeding my daughter for many reasons (so I can build my enough for baby number 2, because my milk will change for baby number 2 and won't be any good for my daughter, she won't grow because it'll be for that of a newborn, she just won't like my milk anymore" but my daughter will not take a bottle for one with breastmilk or even formula. I've tried every single one you could think of and she just wants the boob. Are there really any true reasons why I should stop breastfeeding? Am I really damaging my daughter by continuing to breastfeed??? So many women do it
