Having a hard time eating after having a baby? No appetite

It's been nearly two weeks since I've had my baby. I have no appetite ever. I can go days without eating, because I'm just not hungry. I accidentally went 3 days without food.

It doesn't register with me that I haven't eaten until dinner time. Even then I either don't have time or fall asleep before I can eat.

Even when I do eat, I can't eat much. I feel nauseated by food.

I (maybe) total 3,000-4,000 calories each week. I'm taking a multivitamin in the evening as well, but it's so hard to eat. I either don't have enough time to cook a high calorie meal or I just don't remember that I'm supposed to be eating.

Precooking meals is pointless because they go bad before I remember to eat them.
