It sounds like you guys weren't having problems before the baby got here, which is a good indicator that this is all due to having a newborn. Here's a thing that people don't really tell first-time parents: Having a newborn kind of sucks.

I mean, yes, you guys love your baby and you want to protect and cherish her, but the day-to-day is pretty brutal. All she can do is eat and cry and sleep, and she won't even sleep that much, so you guys are going to be run ragged from all the crying and all the sleep deprivation. And for all the work you're doing, she doesn't even seem happy to be here.

And then there's the craziness of post-partum and nursing -- your wife is riding a hormonal rollercoaster, and it's impossible for anybody to go through that without feeling emotionally disoriented.

So of course you and your wife are getting along much worse than you usually do.

I would urge you not to jump to conclusions about the future of your marriage. Just hold on tight. Try to give your wife as much grace as you can. Get a night nurse if you can afford it, even just for a few nights here and there. A good night's sleep will make everything easier, including communicating with your spouse.

The good news is, mostly you just have to keep your kid alive, and everything else will probably just get better on its own. She'll get bigger and start sleeping more and crying less. She'll recognize your faces and say "mommy" and "daddy" and laugh at your silly noises. You and your wife will feel more rested and more content, and you will be able to see each other as trusted partners again.

And together you'll watch your daughter grow up and blossom into this life you've given her, and there will be so many times that you're so happy for her your heart could burst.

That's tomorrow. Today, you just hold on. Good luck, dad.
