Really angry towards partner

Since about day 6 of giving birth I've become really resentful towards my partner everything he does gets me angry.he is helping out with baby but always complaining that he is tired and needs a nap.

Does he not understand that I've had sleepless nights towards end of pregnancy gone thru a labour and am also now having sleepless nights too I'm so mad.is this normal? Anyone else feel this way? I'm so fed up
