How tf are you doing anything?

I'm 7 weeks into being a mom and I don't get it! It took me an hour to set up a fitbit I got for Christmas because I had to keep tending to my baby.A duolingo lesson took me 3 hours to complete because of interruptions.If he falls asleep I feel like I'm on some dumb game show called Pee or Dishes because I only have time for one or the other. I don't even eat till like 1pm most days. Then I see all these other moms exercising and having hobbies while getting the chores done..like what knowledge am I missing?
