Thanks for all your replies! I didn't know for sure if parents/families were traditionally expected to attend initiation or not. The letter I got was not really specific on that...well, really didn't say anything either way. So I had planned to send flowers, I will order blue & wine colored carnations (hope I can find a place with that combo). I went ahead and ordered her a bracelet, here it is:
Hopefully she will enjoy it. I will ask her the name of her big sis and maybe send her a thank you note with a Target gift card.
Thanks again for your help.
