A.S.
Welcome to parenthood! This all sounds pretty normal, including the feelings that your husband is having. As long as your daughter is continuing to have plenty of wet and dirty diapers and seems to be growing properly, there's probably nothing wrong and she's just going through a growth spurt. You might want to call your doctor and ask about the seemingly constant nursing to make sure there aren't any issues with your diet or the baby's feeding, but most likely everything's normal and it's just the first in a long succession of stages when you'll feel lost until you learn how to deal with it. Take heart!
