My baby is one week old and this is my third child. I'm suddenly getting significantly less from one side when pumping. My nipples are kind of itchy and burning when he is nursing too. I'm prone to yeast but would a yeast infection cause less milk production? What can I use that's natural for yeast? I started taking acidophilus yesterday but what about baby? what if he has it in his mouth? I'm pumping b/c he's not regaining his weight. He isn't losing but he isn't gaining either so I'm pumping after feedings and giving it to him in a bottle. Also, we've had significant trouble with latch so I'm using a nipple shield to make it easier for him (he was born at 37 weeks) and easier on my nipples. Thanks for your input.
