Hi

I still squeezed a bit of milk about months after I finished BF! So I wouldn't worry about it at all - unless you do get lumpy and sore etc

Re : weight - you burn calories BF, so I wouldn't think that stopping BF you would lose weight - just evens out IMO

I would recommend getting fitted as our boobies change with each child - but would suggest you leave it a couple of more weeks so stable shape
