Very specific numbers/rituals

Hey guys, my -ALMOST 4 YEAR OLD 🤯- has been demanding that everything he has is in 3 because he is 3. If he doesn't get them in 3 there is a huge blow up.

He also kind of has a ritual he needs to do before anyone leaves which includes -A kiss, a hug, an Eskimo kiss, a butterfly kiss, a snuggle, a "rub your shirt", and a big hug-

Does this sound normal 😅. I know kids like things in a particular order. But I'm a bit worried it could be some early signs of anxiety or ocd? Of course I could be over thinking this, so I thought I would just see if anyone else's kid has very specific rituals.
