I’m new to breastfeeding but I plan on sticking it through. I have SO many questions! Maybe you ladies can help!

When do I begin to pump and introduce the bottle to my daughter? When I start to pump do I do it during feedings?

My husband has less hours at work then I do so I will be gone most of the day and he will be home. How do I ensure I have a goods worth of milk supply for when I go back to work?

When he leaves to appointments or errands with her how does he feed her without the milk going bad?
