The main trick to work with responsive breakpoints is to design the whole site first meaning adding all the necessary contents on the page and then start adding the breakpoints one by one. If you try to add breakpoint in the middle of adding content to the page it will mess up the design.
If I try to explain this problem, look you added two breakpoints in a page and try to add maybe 10 images on that page, in that case you would have to rearrange them in 2 breakpoints and will be really hard for you to keep track of the elements you are working with. If, however, you add those 10 images in a page and then add the breakpoint life would be much easier.
