My wife just gave birth to our first child. We've read a lot of articles, and have spoken to a lot of nurses, pediatricians, lactatians, and mothers. All of their advises are good, but there just isn't any consistencies. Everyone has a conflicting suggestion with one another. Basically my wife and I would like to know how long can we refrigerate breastmilk. Also, if a frozen breastmilk is thawed in the refrigerator, how long do we have before it goes bad. Another question, if we give our daughter 4oz of breastmilk but she only drank 2oz of it, can we save the remaining breastmilk in the refrigerator and serve it again to her at a later time. We also read an article that it's best not to freeze breastmilk, instead store them in the refrigerator. Is there any truth to this? Any responses is greatly appreciated. Thank you!!!
