Anyone else's toddler obsessed with dinosaurs?

My 4yo will literally only watch dino content, wear dino clothes, read dino books. We went to the Natural History Museum in Chicago last weekend and I thought his brain might explode. He spent 3 hours just staring at the T-Rex. Ran around roaring at everyone. I'm not mad about it, just wondering if this is a phase or if I'm gonna be funding dinosaur everything for the next 5 years lol
