There are moms worse than you -- in the animal kingdom

(CNN)If you're a mother, you have probably experienced the mental "what if" game on repeat since you found out you were becoming a parent.

What if my kid never learns to read? What if they like another parent better? What if their food isn't organic, or I pick the wrong preschool?
Worrying that you're going to fail is normal, and you will make mistakes -- but when put into perspective, know there are moms way worse than you, wrote comedy writer Glenn Boozan in her new book "There Are Moms Way Worse Than You: Irrefutable Proof That You Are Indeed a Fantastic Parent." It was illustrated by Priscilla Witte.
    Those questionable mothers include Dracula ants that suck their offspring's blood, Boozan wrote, and sexton beetles, which lay their eggs on or beside a decomposing mouse and raise the youngsters by feeding them from the corpse.
      The inspiration for Boozan's book came from her shock in learning of her sister's fear and guilt about being a bad mom -- since her sister's "the best mom in the world," she said. "Her kids are perfect angels, and I'm obsessed with them."
      As a comedy writer, Boozan said, "Obviously dumb things come out of my mouth all the time. Instead of some inspiring, beautiful, Instagrammable quote, I responded to her with, 'Well, I don't know. Hamster moms eat their babies. So at least you're not doing that.' And it made her laugh. And she felt better."
      Boozan hopes her book helps alleviate your fears that can be exacerbated by social media, television, advertising and helicopter family members, even "if only for a moment with a little bit of laughter."
        The book is about a 20-minute read you can devour while your kid is refusing to nap in the crib or quietly wiping boogers on the wall.
        Here's the scoop on three other "bad" moms that might make you feel better this Mother's Day.


        Female giant panda Yaya cares for her 5-month-old baby at Chongqing Zoo in Chongqing, China, on January 17, 2016.
        "Panda moms are perfect, until they're blessed with two. Twins are hard, so they'll ditch one -- it's terrible. And true!"
        If a panda has twins, she abandons the weaker of the two since she only has the energy and resources to care for one, according to a 2016 study. Mothering pandas is a demanding job, as newborn pandas can't see, hear, crawl, regulate their body temperatures or expel waste on their own. They need to be cradled for warmth and have their stomachs rubbed to prompt the muscles that help release waste.
        Being able to raise two newborn pandas is rare. "I found out that even in a zoo with completely ideal, controlled environments, usually one of the panda twins won't survive," Boozan said.


        A male koala baby clings onto its mother's back at the zoo in Duisburg, Germany, on March 27, 2013.
        "For dinnertime, a koala mom will feed her kids her poop. Remember that when you feel bad for giving yours fast food."
        The eating of feces or dung is known as coprophagia, which "helps animals acquire the necessary gut microbiome to digest a complex and more varied diet," according to a 2020 review. For koalas, this practice can help them adjust to new habitat
