thrush😔

So my bby was diagnose with thrush in her lil tongue.Anyone else LO Experiencing this . Doc Prescribe us with nystatin some oral drops 4x a day 😞.. I feel like its so much meds. For her 😩😭

My question is I’m breastfeeding n doing bottle as well. They told me to put on my breast but idk how🤷🏽‍♀️ just rub the medicine on my nipple ? N the bottles they say I have to thru em away? Should I use the bottles that she will b using while taking the meds then thru them away? I honestly hate giving her meds so young! I hate it. Augh. I need help with this my doc said give it to her for 7 days? Went to pharmAcy it says 2 weeks wtf (excuse my Language) but why so many days

I always notice her tongue white since she was born too n ask her doc n she said that was normal bc of labor blah blah until she went bk for her 2 months shots that’s when they told us she has thrush on her little tongue.
