Attached Mom,

You are right insofar as tantrums being age appropriate behaviors, since babies and young children know no other way to deal with their feelings or emotions. They begin by crying naturally when upset, lonely, hungry, etc. But they do learn over time that when they cry, mommy fixes it. So they continue to cry to get what they want - being manipulative, but not in a bad way.

The article is saying that you can encourage your child to only cry when it truly is needy. Give your baby attention always and it will not need to cry for attention. Positive reinforcement is important!
