lots of people who are allergic to milk are also allergic to soy...and a lot of soy isn't good for baby boys...there are studies out there that the estrogen levels in soy are to high for devolping little boys thus the "no soy for boy" rule....of course I put 2 of my little boys on soy when they were younger in the transition to milk and they seem to be fine(of course the darn study came out after they were babies)...and in relation to the whole length between feedings...everyone is different....my second son was a "snacker"....he nursed every 20 minutes for 6months(when he started solids) I tried to hold him off several times and he would eat longer and then 20minutes later scream for more food...he's now 7 and still eats all the time and is a rail... none of my other 4 boys are like this some went 2 hours some 3...but not my second...he lives to eat and he eats healthy and is thin... good luck!
