Toddler wants to make friends

[DroopyEyelids]

My 3.5 year old asked me today ‘how do you make friends?’
His speech isn’t very clear. Vocab is fine but pronunciation not great. He goes to a nursery setting a couple of days a week. He is quite quiet and doesn’t chat much to peers from that I have seen. He finds nursery hard I think and seems to be happier at home or in a one on one play date.
I am not a super sociable person but I have a few friends. I’m quite quiet myself.
How would you respond?

Firstly, most three year olds are only just starting to form friendships - most play near each other rather than with each other up until this age. Secondly, I would continue to arrange playdates with kids he knows so he gets that one to one interaction which is a lot easier. And for his question, at this age I'd just say by being you! You're kind, and funny, and I love you so much. If he wants more information after that you can say that he could ask if a friend wanted to play cars? Or another game that he enjoys?
