My son went on a nursing strike at four months old and he did not start nursing again for a month. We recovered from it and went on after that until he self-weaned at around 16 months. Things that helped: me pumping to keep up supply (obviously) and playing with him skin to skin. I got really desperate and would get super upset when I would offer and he would scream instead of nursing, and finally I just decided, maybe he's as stressed out as I am. So I would only try when he was not starving (I pumped and had a really good supply, so that was not such a problem) and I would sing funny songs and tap him with the breast, and after a couple days he wouldn't scream when he saw it. Then, I would tickle his cheek with the nipple, etc., and slowly over about two weeks, I got him to nurse for a minute or two. Then we built it back up from there.
I think if I had not been as dedicated to the idea, had had to go back to work, or had a worse supply, we would have given up. Good luck! I hope it's do-able for you!
