I was reviewing my books today and saw that Tracy recommends discontinuing cluster feeding at 8 weeks. My son is now 10 weeks, gets pumped BM with 4-6oz formula a day, and is huge at 16lb. He takes 4oz bottles between 630-730a, 930-10a, 1230-130pm, 330-430pm then cluster feeds at 6 and 7pm about a total of 7oz. DF of 4oz at 1030pm and wakes once in the night from 230-4am and takes another full 4oz feed. How do I go about dropping the cluster feeding? He's always been the prime example of a baby who eats his way through the witching hours, plus will at most take one 30 min catnap between 4pm bottle and bedtime. He drains his bottles but if I give much more than 4oz he'll spit up constantly and doesn't sleep well. (My daughter was the same way).
