Having never been pregnant with triplets, I can only go on my general knowledge of pregnancy and breastfeeding -- it would depend almost entirely on how much weight you gain (fat and water weight, not baby). Your breast tissue - the glands - don't actually increase during pregnancy no matter how much you gain or how many babies you're carrying. And when your milk comes in, if you are breastfeeding, for a little while you may have very large breasts due to making enough milk for three babies, but after a few weeks that should even out and your breasts will be no larger than any other breastfeeding mama of a similar weight, even without multiples.
