17 Month Old and Throwing Up

My daughter is 17 months old and woke up crying last night at around 11 and then threw up pretty much every hour until about 4 in the morning. She has only thrown up a couple of times today and each episode has been pretty far a part. She is currently asleep now so I am hoping she gets a good night sleep tonight. Do any of you Mommy's have any tips or recommendations on how to make her more comfortable if she does continue to throw up?
