As a newborn, my daughter cried nonstop. Nonstop. Hardly anything worked to get her to stop. I spent the first two months of her life walking around with her in the upright position, over my shoulder, because that seemed to be the only way she wouldn't cry. Newborns cry since the moment they are born. They cry when they are hungry, sleepy, cranky, wet, in pain, or just because. Their cry makes you question whether life is worth living which ends up being one of the many things every mom thinks when her baby cries.
My daughter had difficulties breastfeeding, so she cried because she was hungry. When I realized I should start pumping, she cried because I didn't produce enough. When I started supplementing with formula, she cried because her stomach hurt. Then she had colic. Then she had acid reflux. She decided sleeping was for the birds, so she cried instead. She cried at night because she was exhausted (crying all day is hard work, after all) and we couldn't figure out how to soothe her. She cried the moment she was wet. I mean, like a teeny tiny little sprinkle in the diaper would set her off. She cried like crying was the only way to live. She cried like crying was a right and a form of protest.
A crying baby is possibly one of the worst sounds in the universe. It's worse than a fork scraping on a plate and even more heinous than nails on a chalkboard. It makes one insanely sad and wildly angry at the same time. It's all very irrational, but it's also normal, which is why the following thoughts are pretty damn universal when a mother is holding her crying baby. Hang in there, mom.
