Help with a hat

I screwed up. I’m making a hat with earflaps. I was supposed to increase 2 stitches and then work in stockinette 4 inches, then start to decrease. I didn’t do the 2 stitch increase, and I’m pretty sure I am not frogging to do the increase. What can I do now? I can’t decrease evenly as the pattern says because I don’t have the right number of stitches. Help?

I would leave out two of the decreases and just spread the rest evenly around, if you think that would work with the pattern you’re using.
