my ds (10 wks) is doing the exact
same thing - left breast only. what i'm doing right now is just nursing on the left, pumping on the right, so i don't get too lopsided and uncomfortable, and so, if he does get over the preference thing, i'm not closed for business on the right
. he does take the right breast if he's really really hungry, but only until he realizes he's been snookered - then he fusses for the left again. odd...
anyway that's about all the advice i can offer as we're trying to figure our way through this as well... good luck!
(on the upside i am
managing to stockpile a large emergency breastmilk supply in my freezer...)
