So besides your husband, you have no other adult help, it sounds like? And you have some older kids too?
Husband works at night? Is that why you are on your own at night?
Your pump output sounds entirely normal, - how many times per day you pump?
What is your goal? If you could wave a magic wand and have whatever you wanted, would you like to nurse baby at the breast, or nurse combined with pumping and bottles, or both combined with formula?
A baby this age wanting to be held pretty much constantly is normal. Do you have a baby sling or wrap? Does baby sleep near you?
What happens in the hospital and the information you were given there about the first few days of nursing is basically irrelevant at this point. Just about everything about breastfeeding changes dramatically in the first few weeks. If you are also dealing with a recovery from a c-section, you body and mood also tend to change dramatically in that time.
You cannot tell anything about your milk by looking at it in a bottle. But there is absolutely no reason to think anything is wrong with your milk.
If you want to get more informed about breastfeeding, this website and
www.kellymom.com are good general info online resources, and the book The Womanly Art of Breastfeeding (8th edition) is an excellent book.
