Just call her out more OP and embarrass her. Like “wow, that’s so weird you tickle your grown son, even when he says to stop”. And it is weird.
That seems like a bad idea. There’s pretty much no way to say it and not offend MIL and come off looking like the mean DIL. Of course MIL is wrong, but it’s between DH and MIL. Of course you could ask DH if he wants you to talk to his mom about stopping the tickling, by I wouldn’t do it without discussing it with him first. He’s an adult, knows his mom very well, and can decide if he wants to pursue it. If MIL could be reasonable about the discussion, it might be okay for OP to say something, but if she were reasonable, OP wouldn’t need to say something.
