Back of daughters neck

Carmen • Expecting our baby girl December 15 💗💗💗 👶 6.16.17 wedding date. Massachusetts girl in the sunshine state. Disney lover annual pass holder ❤️ dog mom to my puggle

It’s only getting worse she does have baby acne that goes near this spot. But my worry is that it could be from my body wash ? Detergent limy clothes? I hold her in my arms when feeding her bottle and I’m freaking out it’s one of those things and she goes to day care in a few weeks what if one of those infant teachers sets it off mire ? Help !
