basically the time between feedings can ONLY be regulated by the individual mother and baby physiological pair.
Daly et al. (1993b) used the CBM system to measure the changes in breast volume of seven breastfeeding mothers over each breastfeed during a 24 h period. From these measurements they could determine the maximum and minimum volume of the breast over the 24 h period, the storage capacity of each breast (maximum-minimum breast volume), the degree of emptying of the breast, before and after each breastfeed, and the short-term rates of milk synthesis. They found that the storage capacity of the breasts ranged from 80 to 600 mL. The breast was not necessarily completely emptied at each breastfeed (Mother A; Fig. 8), indicating that the infants regulated their milk intake presumably according to their appetite. Daly et al. (1993b) suggested that the storage capacity of the breast influenced the frequency of breastfeeding. Compared to mother A, mother B had a much smaller storage capacity and her infant nursed more frequently. By more frequent breastfeeding this infant was able to obtain at least as much milk as the infant of mother A (956 vs 896 mL/24 h, respectively).

Wow, that is really interesting information. I'm so glad to know there are good studies being done to help us understand these things. I think that prolly sheds a lot of light on individual differences in babies' nursing patterns.
I wonder if there's any difference from baby to baby for the mom? Ykwim? I noticed that my first child nursed a whole lot longer and more frequently than my subsequent ones. But with all the others (#2,3,4) I was tandem nursing, so presumably my milk supply was a lot greater due to nursing two. If I fed the newborn first, then he/she prolly got a lot more milk per feeding and didn't need to feed as many times or as long per feed. Do you suppose? I always sortof assumed that was so. This research would certainly suggest similar.
I wonder also, if there's anything a mom can do to increase the storage capacity of her breasts or if any factors in the early stages affect that (like moms being allowed to have babies co-sleep and nursing on demand, etc)?
Oh, the possibilities for studies are endless.
About the ped, I'd take a friendly and curious attitude, as in "Gee, do you think so? I know you've said that before, but I haven't been able to find any information on the benefits of spacing feedings, other than convenience for the mother. The things I've read in ________ (name your sources) all say that babies should be fed on demand and that their needs will vary (even cite this study). I'd really be interested in any literature or references you might have about this..."
