Crazy about nursing

Is anyone’s nursling becoming more obsessed with nursing rather than slowing down? My son is crazy over it. If I sit down he immediately comes to me signing milk, saying “titi” and sticking his hands down my shirt. Or if I pick him up he does the same thing. He’s definitely not hungry. I’m wondering if it’s maybe because he’s bored but even if he’s occupied he will stop whatever he’s doing when he notices me sit down. It’s starting to drive me a bit crazy bc I can’t even sit for five seconds. If I don’t let him have “titi” and try to redirect to something else he has a screaming fit.
