DS turns 3 next month. We are planning a small party at home for him. I'm going to invite a couple of his friends that we know from his swimming class and from our NCT group with whom we have had play dates before. When I ask DS who he wants to come to his part he always mentions a boy who goes to his nursery.
I'd like to invite him as well but have never actually seen the boy or met his parents (he is from an older class but the nursery workers confirm that they are friends and often play together).
Would it be odd at this age to just invite the boy (and obviously his parents/guardian) to the party or should I arrange for him to come to our house to play at some point before the party?
