Abstract: A planning system is provided for planning breast feeding or milk expression. An input receives first milk flow information from breast Schedule pumping sessions and second milk flow information from breast feeding sessions. The first and second milk flow information are processed to derive a input schedule, wherein the schedule specifies a combination of future breast pumping and breast feeding sessions. In this way, the system assists a mother in planning her milk production routine to best fit with her schedule as well as providing the best nutrition for the infant.
