Extreme sleepiness after having my baby

I’m 2 weeks postpartum and I’m extremely tired all the time I pretty much sleep all day long besides when it’s time to feed her then go back to sleep I do this through out the day and night time. During the day I’m awake for maybe 5-6 hours consistently sometimes. My boyfriend even has to wake up during the night to feed her because I’m to tried to wake up and feed her but I feel like I’m sleeping SO MUCH. I took iron pills through out my pregnancy should I keep taking them? Is this normal even when I’m awake I’m so fatigued and just want to lay there constantly I don’t want to do anything
