I couldn't nap during the day no matter how hard I tried and don't think everyone can. I would get so annoyed (no offense) at the sleep when they sleep advice. I have just gotten a lot better at life on little sleep. I go to bed shortly after ds does and my schedule is just different than it used to be.
OK, obviously doesn't work for everyone.The point behind my comment was moms often feel like sleeping during the day is not even an option because they have to take care of XYZ around the house.If you can sleep during the day, take advantage of that. No harm meant.
