Hi Isabella! :waving: Welcome to the forum.
I’ll take a stab at your problem. I don’t know what type of increase you are using, so I will “demostrate” with the knit front and back type (abbreviated KFB). So when you are knitting along and are told to “inc into next st” you do:
K to instructed place, KFB, continue K according to pattern.
Now when a pattern says “inc into next 2 st” or “inc into next 4 st” they are telling you how many times in succession to do the increase. So that would be:
K to instructed place, KFB, KFB, continue K according to pattern. OR
K to instructed place, KFB, KFB, KFB, KFB, continue K according to pattern.
Note that the increases are done in successive stitches, not the same stitch - which it what I think your problem may be. As Brendajos said, it may be a little tight but the end of the 4 consecutive repeats, but it is doaable. Also, if the pattern does not specific the increase type, you might experiment with different styles to find which one is easiest for you to work. Good Luck!
