In reading articles and books (my favorite is "And Baby Makes Three" by John Gotman), a lot of advice is to make sure to prioritize your relationship with your SO and even prioritize it above your relationship with your child. I recognize this may not be the focus or seem like a popular opinion, especially because we all have such new little bundles of joy that require so much attention right now. But overall, to me, it makes sense. If your relationship with your SO isn't strong, then it's going to be harder for you both to be happy, healthy and in a good spot to parent your child together.
So my question is, for FTMs...what are you doing to actively prioritize your relationship with your SO? For STM+s, what have you done in the past that has worked well?
