No, but now days, I'm not surprise to see kindergarteners with them 😳.
I think it is more appropriate to have friends during this age.
Boyfriend/Girlfriend is not a game. It is a relationship status and it has responsibilities. Friends are better.
Childhood infatuations (puppy love), is normal to the point of stealing awkward glances and maybe holding hands . . .
There was Stacy Watts that I had a crush on, but Mary Beach was my best friend. I did everything with Mary . . . Ride bikes, go to the movies, go to the local Fair, walk to the general store for candy . . We even built our own Haunted House in my attic.
yes its normal.
