I'm worried for my toddler. When do friendships come?

Toddlers play with whoever is there. They make friends out of nowhere. I think most of the time friends end up coming. And kindergarten, up to fifth grade. Some kids don't have the same friends throughout those. Early years I would not worry at all. I would think about your own friends and realize that not all friendships that start at such a young age will be lifelong. Maybe they will. My son has one friend and I'm also friends with his mom. So I think they'll be around for a long time. And maybe they'll end up being best friends. But there's no guarantees.

I’d say most of the friends are made in primary/elementary school as they are a bit more attentive to who they like playing with etc. My son is almost 9 years old; he made friends in daycare/preschool that we still invite a few to his birthday parties (although he’s replaced a handful with school friends now), but his first “best friend” we only see a couple times a year is from daycare and then he has his neighborhood/school bestie along with another handful of school friends.
