One side feeding and pumping

Lferr417

So lo only eats off one breast... But my question is when I start pumping for my return to work at 10 weeks pp what's the best way to do it.... Only pump the opposite side or pump both?? I plan on feeding him off the breast when I'm with him at night. When I pump at work I plan to pump both but don't want to create and over supply... Or under supply...

Also for one or two bottles here and there now what's the best way to not over stimulate??

Sorry such newbie questions here I'm just not sure what is the best way to do it!!
