LO is 7.5 mo and I've always kind of offered a feed every 1.5-2 hours (we still EBF since he doesn't seem ready for solids). He's always had digestive problems (intolerances?) and it was suggested that feeding less and more frequently would be easier on his system. These times also coincide with him going down for a nap/waking up (he got very distractible and these were the times he fed best).
Both our regular pediatrician and a homeopathist have suggested to me that this is too often. Can you really offer the breast too often?
