1. A device for measuring an amount of breast milk suckled during a breastfeeding session, the device comprising:
- a mechanism for determining a change in volume of a breast from before the breastfeeding session to after the breastfeeding session, said mechanism including a mechanism for measuring a quantity of fluid introduced into a space of defined volume around the breast, first before the breastfeeding session and again after the breastfeeding session, and providing an indication thereof; and
a calculation unit for calculating, from said measured quantities of fluid, a change in volume of the breast and a quantity of breast milk suckled during the breastfeeding session, wherein said calculation unit is coupled to said mechanism for measuring, receives the indications of said measured quantities of fluid in the space around the breast and calculates said quantity of suckled milk from a change in said measured quantities of fluid measured before and after the breastfeeding session;
wherein said calculation unit comprises an electronic board including;
a memory chip; and
a micro-controller chip.

10. A device for measuring an amount of breast milk suckled during a breastfeeding session, the device comprising:
-
a mechanism for determining a change in volume of a breast from before the breastfeeding session to after the breastfeeding session, said mechanism including a mechanism for measuring a quantity of fluid introduced into a space of defined volume around the breast, first before the breastfeeding session and again after the breastfeeding session, and providing an indication thereof; and a calculation unit for calculating, from said change in volume, a quantity of breast milk suckled during the breastfeeding session, wherein said calculation unit is coupled to said mechanism for measuring and receives the indications of measured quantities of fluid in the space around the breast and calculates said quantity of suckled milk from a change in said measured quantities of fluid measured before and after the breastfeeding session; wherein said mechanism for determining a change comprises; a fluid chamber coupled to said space forming a closed system; a piston sealingly mounted in said chamber for slideable movement therethrough; a fluid pumping mechanism coupled to a driving chamber, the fluid pumping mechanism introducing and removing fluid to said driving chamber for driving said piston through said fluid chamber; and a mechanism for indicating a quantity of fluid pumped into or removed from said space selected from the group consisting of; a position encoder for indicating a position of said piston; and a timer and flow-rate meter coupled to said pumping mechanism for measuring a flow-rate of fluid that is introduced to the space of defined volume around the breast and providing an indication of time during which said pumping mechanism was pumping and said measured flow-rate to said calculation unit for calculating change of volume.

11. A device for measuring an amount of breast milk suckled during a breastfeeding session, the device comprising:
-
a mechanism for determining a change in volume of a breast from before the breastfeeding session to after the breastfeeding session, said mechanism including a mechanism for measuring a quantity of fluid introduced into a space of defined volume around the breast, first before the breastfeeding session and again after the breastfeeding session, and providing an indication thereof; and a calculation unit for calculating, from said change in volume, a quantity of breast milk suckled during the breastfeeding session, wherein said calculation unit is coupled to said mechanism for measuring and receives the indications of measured quantities of fluid in the space around the breast and calculates said quantity of suckled milk from a change in said measured quantities of fluid measured before and after the breastfeeding session; wherein said mechanism for determining a change includes; a breast interface for placing on a breast, said breast interface defining an internal space; a fluid pump coupled to said breast interface for removing fluid from and introducing fluid into said space; a control mechanism coupled to said fluid pump for indicating to said pump to start or stop pumping; and a mechanism for indicating a quantity of fluid pumped into said space until said pump was stopped; said device further comprising an incorporated breast pump including a breast pump cup and a breast milk/air separator coupled to said pumping mechanism.
