Many books do not state the reality of night feedings and the intense need some babies display for them. You also can try getting a nap in the afternoon to compensate.
You wouldn't believe this but while in college I majored in child education, and the very books required to be studied and read were in majority authored by men. ( who spent more time in an office than with children) And one book in particular was about child behavior and how to manage it. I flipped to the back page where I read that the author dedicated this book to her twins, so and so: THEY WERE HER PET DOGS!!!!! The author was not a parent.!!!!!!!!
And for lack of sleep Ihave noticed when Im taking my vitamins and supplements my energy level has soared.
