Post pardum health

I’m a ftm and am constantly tired! Like I do not want to do anything really until like 2pm. I want to do things but some days I just would rather rest. If we do have a day we go out the next day we have to take a rest day to almost like recover. So anytime baby goes down I have been too. Is this normal? I feel like so many other mamas or things I read are like I’m up by 7Am showered and ready to go. Some days I wonder if I’m just being lazy or something but I’m so tired. Baby is now 4months and so we have hit a sleep regression which is why I’m more tired now then usual but still even before 4 months it’s been pretty similar.
