Every parent dreads the thought of their baby crying. But despite your best soothing efforts, they will cry and sometimes it will drive you crazy, especially if your baby is teething, has colic, or is going thought any other particularly tears-inducing phase. As time goes on, you'll learn the best ways to calm your little one down. There are, however, a few things you should never do to get a baby to stop crying that you should take off your "soothe list" ASAP.
These things, while mostly intuitive, are vital for parents to know for their baby's safety and their own sanity. I'll be the first to admit that caring for your baby when they're crying can be frustrating. It can test a parent's patience, cause them to worry that something is wrong with their baby, or even act irrationally. However, doing the following things to try and calm your baby can harm them physically or emotionally and are generally ineffective at best and dangerous at worst.
Instead, using proven techniques like Harvey Karp's "Five Ss" method — swaddling, side or stomach holding, shushing, swinging, and sucking (or nursing) — will help rule out possible reasons your baby may be crying one by one and likely be much more effective than these things on the "not to do" list.
