This is an important lesson. No one cares about your lack or sleep, so MAN UP! With that being said, you are still human and there may be an occasion where you just need to recharge. It’s better to tell your partner when you’re close to feeling beat, than to hold it in and reach a breaking point. Sleep-deprived conversations can lead to anger, and snapping at each other, when all you need is a little time in bed. Tell her in advance when you’re feeling sleepy. Together, you can work out cues when you need to take a nap, or need to go to bed early. Before hitting the sack, she’ll probably give you a few small tasks like replacing the diaper genie, taking out the recycling, or watching the baby for a few minutes while she goes to the bathroom. Once you’ve given her some time, there’s a good chance you’ll get a chunk of time to yourself. Just make sure you’re ready to take over when she hits the wall.
