I EBF my 9.5 month old and have no idea how many oz he takes in a session or a day. This weekend DH and I are going away overnight for the first time since both kids were born! I'm pumping for the first time since DS2 was 3 months old to leave milk with MIL who will have the boys. How much should I leave for this 24 ish hour period??? How much does your 9/10 month old take in a session? Before bed? In a 24 hour period??
