Quoting Brendan&Bethany'sMom:" OP I hope you don't mind but I have a few questions myself. Do you warm the breast milk for the baby ... [snip!] ... bottle will he ever latch to me again? Will a pacifier be bad to give to a breastfed baby... will it cause latching issues? "
My boys didn't seem to mind cold bm so I didn't always warm it if they were really hungry. If I had frozen milk I would simply run it under warm water to thaw which would take care of the heating it up process. Otherwise, to warm, I would put the bottle in a bowl ful of warm/hot water for about 5 min and it would be plenty warm. I would usually pump after a feeding to make up for the first few days I would be at the college and then I would pump during my lunch break in my car (you would have laughed to see how I had blankets pinned up for privacy, it was that or the bathroom, yuck) and store the milk in a cooler to put in the fridge when I got home and to use the next day. After the initial buildup of a few bags of frozen and some fresh for the first few days, I only pumped while I was away from home, since breast milk can last a week in the fridge, friday's pumped milk was fine to use on monday. If you pump even when you are with baby you can create an oversupply of milk that can be extremely uncomfortable if your in a situation where you can't pump for a few days and baby isn't emptying you. Some babies may prefer a bottle as they don't have to work as hard for the milk, although mine refused the bottle after the first few tries so it was never an issue for us.
If anything, baby can be spoon fed bm as well if your LO refuses bottles like mine did. My boys both ended up nursing all night to make up for their skipped feedings while I was at school. It as emotionally hard on me at first, but they seemed just fine. This was a case where cosleeping was an absolute necessity, lol.
Oh, I never used pacifiers so I can't really comment on that other than to say they are best avoided until your supply has evened out as the sucking baby does on the pacifier may actually be because baby is hungry and thus your breasts are not getting that signal to create more milk. Also, you'll be so engorged at first you'll be more than happy to be used as a pacifier.
