Our first 5 year old!!!!! What a milestone for the board. I can't believe we've stuck together for 5 years.....almost 6 since we got pregnant.
I don't think there is anything wrong with just inviting the kids he's known from previous years as long as you do it discretely. I mean, seriously, you can only invite so many. Cameron is in Junior Kindergarden this year and the policy at his school is that the parent can provide special treats on the child's birthday for everyone in the class. If there are invitations to a party, they are to be handed out discretely at the end of a school day. If they are handed out in the morning before class, children not invited may be upset. And the invite is most appropriately handed to the parent.
