So, it turns out you can’t just install your baby onto your chest (like a car seat, top-end up and rear-facing), then just kinda expect feeding to happen. Nope, you are the car seat! Which means you’ll have to figure out how to buckle your baby around the boob using the rest of your body.
If you’re new to holding babies, don’t stress if you thought you’d instinctively know how to hold yours while nursing. Sometimes, a change in positioning is all it takes to make breastfeeding snafus less snafu-y. Most likely, you and your baby will find a favorite position that works best with each age and stage.
