Natashia, are you breastfeeding or have you breastfed? If so you need to wait 6 months after you dry up from breastfeeding before starting. If not then I would suggest waiting another 2 months to make sure you are dried up, pumping can induce your milk production to start back up. I know you're excited to start, but it really is best to wait. I waited 9 months or so after I stopped breastfeeding before I started any NBE. As far as a smaller breast... one of mine were smaller than the other, what I did was I pumped the smaller one with more pressure and for longer periods than the bigger one, and over the year I have been pumping they are almost completely even. Just one is slightly wider than the other now, but not bigger otherwise. Hope this helps and good luck!
