DS is nearly 8 mo. When he was about 3 mo he suddenly decided he preferred my left boob. It has always been slightly larger than my right and more markedly so since bfing.
For the last few months he would sometimes feed on the right (usually when dopey) but more often than not would pull off and fuss. I always offer the right first as I know they suck strongest at the start of a feed, then swap to left when he fusses, then right again, but in the last few weeks he's barely fed on the right at all. Instead of fussing, he pulls off, looks at it thoughtfully and starts twiddling it with his fingers 
I don't express much but when I do I get markedly less from the right. The size difference is quite noticeable too (I've stopped wearing Breton tops and DH calls me Kim Basinger
).
DS has never had any formula and is doing v well on solids.
Is it OK to just feed from one side? And am I doomed to have hilariously lopsided norks?
Has anyone had the same experience? I've read that the size thing evens out when you stop bf - is this true?
