I thinks so much depends on where you want to end up. Breastfeeding for me was very easy. My boys latched on like a champ, I never had letdown issues and could breastfeed just about anywhere, no pain, no infections, it was truly a cinch. Much easier than formula for me, and cheaper! However, that was my experience. I have plenty of friends whose experiences were the polar opposite.
I think a lot depends upon why you're supplementing with formula and how long you hope to breastfeed. To be totally honest, two to three bottles each day will have a definte impact on your supply. Is your situation one where you really need the bottles during the day? Also, were it me, I would want to stimulate my daytime supply as much as possible, ie, give all feedings then if it's possible for you, so that your milk supply is ramped up for the daytime and baby has plenty to eat. This will be good for when baby's ready to drop nighttime feeds.
