From the first night, LO has always preferred the left. Because of this I default to the left if we are somewhere that could be tricky for nursing (lots of distractions, or not ideal place to be able to nurse semi-discreetly or comfortably). I also use nipple shields due to flat nipples, and I have not been able to wean from them yet. I haven't had any issues with the nipple shields other than the inconvenience of them. Because she does so much better with the left, I have ended up with far better supply on that side. When I pump, I get usually at least 2 ounces more on the left.
