It's completely normal to feel surprised and unsure about changes in her body, and what you're experiencing is a natural occurrence that can happen to some women, especially those who have been pregnant or are breastfeeding before.

While it may have caught you both off guard, it's important to remember that this is a variation of normal and there are ways to manage it. In fact, some people even induce lactation on purpose for various reasons.

I recommend doing some research together to better understand what's happening and discussing your feelings openly. You can find more information at The Lactation Wiki (https://lactation.wiki), and if you're in the Houston area, check out ANRHouston (https://anrhouston.com) for local resources. It's crucial to maintain open communication and support each other during this time. Remember, this unexpected event doesn't have to negatively impact your relationship; instead, it can be an opportunity to learn and grow together.
