Re: Pumping for a bottle feeding
If you are going to skip a feeding and let your husband give a bottle, you would need to pump during that time so your body doesn't miss a cue to produce more milk. So that would cover your one bottle a day. That said, if I were you I'd wait a few more weeks to skip a feeding, just to make sure you don't affect your supply. It's so sensitive that first 6-8 weeks.
If you decide not to skip a feeding, I'd normally say the best time to pump is in the morning after one of your nursing sessions. Most women have higher production in the morning. But if you already have problems getting engorged, I'd caution you once again to wait a few more weeks before you start pumping in addition to nursing. Because pumping in addition to nursing is definitely going to tell your body to make more milk and you definitely don't want to pump your way into oversupply, which can happen with women who tend to produce a lot of milk.
5-6 weeks is typically the time moms who want to pump will start pumping, though usually it is in preparation to go back to work and will be replacing feedings with pumping sessions. For a mom who isn't planning to go back to work, I'd personally recommend they don't start pumping until 6-8 weeks because your supply-demand balance is so sensitive.
