SQ 1st School Birthday Party

SQ 4 years old birthday will be coming soon. Her teacher already request me to ready a birthday cake for SQ’s classmate, they will have a small celebration party for her. I wonder should I print some birthday invitations card to SQ’s little friends or not. Maybe I should invite children’s parent to enjoy the party. Hmm...However, is it possible to arrange a party for our parent as well? I think I better arrange the party at weekend to ensure all the parents is free from working.
