3. Letting your baby cry it out can cause emotional damage
Babies who are left alone when they cry are known to be stunted emotionally and shut down from the outside world. They find it hard to trust adults and stop feeling and growing. This can lead to permanent brain damage and a number of emotional issues which can last throughout life. Next time your kid starts crying at night, get up and cuddle him/her. A little affection will go a long way.
