Re: 2 questions about milk supply
Welcome to the forum and congratulations on the new baby!
In general, a mom who is home with her baby can maintain supply simply by feeding on demand, which means nursing as frequently and for as long as the baby wants. As babies get older, stronger, and more adept at nursing, they often shorten their nursing times so that they get all the food they need in a short time, often as little as 5-10 minutes. It is not necessary to "empty the breast" every time you nurse, firstly because the breast is never really empty (milk is ALWAYS being made, and the emptier the breast gets, the faster the milk is replaced), and secondly because of the supply = demand equation. If the baby leaves some milk in the breast and supply drops, the baby nurses more often and the frequent demand boosts supply back up where it needs to be. Eventually, your supply and the baby's demand will be very closely matched, and at that point you will rarely if ever feel full or engorged- but remember that soft, empty-feeling breasts are NOT actually empty!
I suggest that you put away the pump and simply enjoy nursing the baby.
If you can share more about your first 2 nursing experiences, we may be able to reassure you.
