Re: Bottle vs breast - how many ounces?
You can't over feed a breastfed baby. The very best thing you can do is let him regulate his own feedings. 3-3.5 ounces is a little high (but not excessively so) for that age, but every baby is an individual and has unique needs. Just keep feeding on demand and let him nurse for as long as he chooses and he will thrive. Breastfed babies can pack on a lot of weight early on (mine gained a pound a week for awhile) then thin out later on as they become more active.
Wait for your milk supply to regulate a little more before you worry about pumping. Pumping can aggravate OALD (speaking from experience) and lead to oversupply. Unless you are going back to work soon, you are best off letting your baby regulate your milk supply rather than the pump.
