Babies sleep through the night when they are ready to sleep through the night. Giving the baby solid foods in the first few months when the gut is unable to digest anything more than human milk often allows a food sensitivity to develop which the baby may never outgrow. They grow fast. If they continue to grow as they do in those first few weeks, they will be 22 feet tall at age 10 years. Feed when hungry.
Breast milk is low in fat and protein so is low in substainability.
The babies like and need this also. You will spoil him. If babies are responded to quickly in those first few weeks, they cry for shorter times later. Ninety-six percent of habitual finger suckers have been left to fall asleep alone after feedings when they were smaller. My only criticism I could muster up about this book is that she did not suggest a chiropractic examination of the baby in that first week or two of life.
