DS takes expressed bm and 3 meals per day. He has 6ozs morning and afternoon and 8ozs at bedtime which is the maximum volume the large bottle takes. He continues to suckle when he finishes the 8ozs although does not create a fuss when I take the bottle away. He wakes usually once in the night but I do not feed him and his morning bottle is at 7/7.30am. Should I offer more from a second bottle (hoping it might help the night waking) or assume he is satisfied since he doesn't cry for more?
