For a while after giving birth, most moms can't imagine being separated from their baby. Eventually, though, self-care comes into play (whether you've thought of it yourself, or someone who loves you has said that it's time), and you need to get out of the house on your own and at least for a little while. Still, no matter how necessary that initial outing is, when a mom's partner is alone with the baby for the first time, things are going to get challenging. And by challenging, I mean simply existing as a put together human being can be difficult. Make no mistake, your baby will definitely survive, but whether or not you do is an entirely different story.
I remember, when I had my first child, I had real problems leaving her. I'm guessing the source of my extreme hesitance was related to some of my early anxiety rearing its ugly head, because from the day we brought her home, I didn't want to leave the room without her. So if that's what you're feeling, you're not alone.
When I was finally able to leave her in the care of someone else, even for an hour or two, I felt a physical pull back home, deep in my gut. By the end of my time away, I was crawling out of my skin, ready to leave wherever I was far too early and head on home to my baby. I had a weekly choir practice to attend, and it was tortuous. Eventually, I got over it (I'd like to think it was self-preservation, but if I'm being honest, it was likely finally going on medication to control my anxiety), but I sent many, many texts to my partner on the first night our baby was in his sole care, and many nights since. In fact, they looked a lot like the following 12 texts I'm just going to go ahead and tell myself every mom sends her partner when she's away from her baby for the first time.
