Circles

Does anyone else’s toddler love finding shapes? My son will point out and find every circle he can. Doesn’t matter how big or small. We will be walking in a store and see a mark on the floor that’s a circle, or on the street one of those sewer covers. If it’s small he will just point and touch it. If it’s big enough he will walk in circles within it.

Is this normal observant behavior for toddlers? He doesn’t spin in circles much but knows how to do it if he sees others doing it.

FTM so I don’t know if it’s all normal and learning everything or what! Lol
