Nursing and pumping

The time has come for me to stop nursing and pumping. I have given Fisher 12 weeks of my milk. I am feeling a little on the sad side though, because I wanted to keep giving him my Milk for a lot longer but since I have been back to work I can not keep up with him so I feel that it is time to let it go. I am still pumping but just not as much so once I dry up I will be done :(
