-- my experience ( I nursed 3 babies -- for up to 14 months- and kept 'em off solids for as long as I could) -- is that when I did wean-- within a few months- my breasts were identicle in size --- and I didn't have a lot of changes in my breasts with weaning ( yes, of course they were smaller - but they were about what they'd been before each baby was born - in size and equal'ness and so forth--- be calm and all will work out --
that was MY experience-- ( aren't babies incredible???)
love,
