My daughter has a MAJOR preference for my left side.
There’s no set way to do it. Just be sure you wean off bf and/or pumping that breast gradually. Keep an eye on that breast and make sure it’s not getting overly full and if it is bf or pump on that side as much as needed to maintain comfort and you’ll soon see that it’s not getting full or uncomfortable and you can leave it alone.
I think you might just be done on that side, seems like more trouble than it's worth to keep worrying about it, kwim?
You say the diapers
She doesn't get anything to drink besides my boob.
