2 Year old Reflux

My daughter will be 2 in June and for the past three nights she has thrown up while she in the midst of going to sleep. She has no fever nor diarrhea. She doesn't throw up at all during the day and she is very active (no changes in her mood or activity) Her doctor is on vacation until Wednesday so I spoke with her assistant and she believes that she might have Acid Reflux. She couldn't confirm it because the Dr. isn't here but does it sound like Acid Reflux to you ladies? If so, what are some things I can do to help her? I haven't changed her milk or anything so is there any solution? The Dr's Assistant said they would have to prescribe medicine for her....are there any natural things I could do? Should I stop giving her a bottle before bed time? Any suggestions would be so helpful!
TIA
