yes. feed this L on the smaller side more often but dont 4get to put lo on other side as well. i did this with the son and daughter. with my son my right boob became larger and i decides that when i had my daughter to feed her off my right and a little off my left and im glad to say today that my boobs are now the closest you can be to even breasts
I think you should sit down with a good lactation specialist prior to birth. Discuss your concerns and your experience and see what she recommends. There are women with large breasts who ARE able to breastfeed but require the use of aids. I see no reason why you couldn't do as you are saying, the only thing I can think of is that if you are planning to feed to the pumped milk from a bottle it may cause initial confusion and frustration for the baby. Maybe you could invest in one of those supplement contraptions (not sure what they are called). The ones that you hook a bottle into and it has a little tube you insert in the baby's mouth while s/he is nursing on your breast.
There is also the idea of simply pumping both sides and bottle feeding the breast milk. I would really speak with at LEAST one, if not a few, lactation specialists. Good luck.
