My partner is awesome. And let me tell you why.
C has been waking up a lot in the night. Not always to nurse - in fact, most of the wake-ups are not for food. So the other night A (my partner) said I will handle all wake-ups tonight, your job is to sleep. If we need you for food I will wake you and bring her into bed and when she is done I will take her back to her crib.
So all wake-ups were taken care of (and I wasn't needed for food). Do you know what it is like to get that much sleep? It was like 8+ hours. And I trusted that A and C would figure it out (a nice little bit of surrender on my part) and so I slept.
The next day I was so pleasant and happy and easy going.
