dry nipples?

Ke

No question is a stupid question, right? this is my first pregnancy and I've noticed my nipples are extremely dry. Does anyone know the reason for this? I use 100% Raw Shea Butter as my lotion and it seems to be helping but by the end of the day before/after my shower they are SO DRY again! I've been guzzling water like crazy so I know that isn't the problem. Can anyone help with this?
