PIECE OF NICOTINE FELL IN BABIES BOTTLE

so I’m LITERALLY GOING TO HAVE. Stroke! My mother watches my baby, she doesn’t smoke around her. But rolls her own cigarettes! I don’t smoke. I picked my daughter up and got home and went to wash her bottle out, and there was the tiniest piece of nicotine in the nipple of the bottle. I am seriously freaking out. I’m crying my eyes out! I don’t smoke I don’t drink! I never wanted her to subjected to any of that! Please tell me my baby is going to be okay! She is 7 months old :,(
