baby shower

My family is throwing a surprise baby shower for my eldest sister and I was assigned to take care of the souvenirs to be given out to those who will come to the baby shower. Since the people on the guest list consist of adults and children alike, I was thinking of a souvenir that would be appropriate for all ages (I also don't have much time to buy separate tokens for adults and kids). My budget is about $3 per souvenir since we're expecting around 80 people to come. Need your help again guys ~

It's my cousin's baby shower next week. I'm really excited about it because this would be my first time to attend such kind of event. I would really appreciate your suggestions a lot. Thanks!
