During the first year of life, a baby wakes up frequently during the night. As you have now learned, this is not a problem. It is a biological fact.
The problem lies in our perceptions of how a baby should sleep and in our own needs for an uninterrupted night’s sleep. We parents want and need our long stretches of sleep to function at our best in our busy lives.
The idea then is to slowly, respectfully, and carefully change our baby’s behavior to match our own needs more closely.
