Welcome to the forum,
You'll find alot of support and advice here. First though, you'll need to provide some more information.
How old is your son? How long has he had Crohn's symptoms? Has he had any diagnostics done, and if so which tests?
If he's still on 40mgs of Prednisone, then he's pretty much just started it. He'll be weaning off for about 8-9 weeks. He should start feeling better very soon, but it sometimes takes a couple of weeks. Make sure you stick to the descending dose schedule strictly. You can't just stop taking this drug.
At this point along with the Prednisone, I would only recommend you follow a low residue diet, and stay away from avoidance foods. Your GI should provide you with the information you need.
