Oh getting them on a schedule is so hard and you definatly don't want to give her medicine she doesn't need because it will cause health problems down the road. Tracy Hoggs is a fantastic Nanny that they call the baby whisperer. Her specialty is getting kids on schedules so they sleep and eat right. She is a big believer in schedules.
What does your daughter do that she "refuses" to go to bed? You have to be strong and put her down at a reasonable time, whether that is 7 or 8 depending on your family.
A lot of time babies have a hard time going to sleep because they are over stimulated. Just like us, they need time to calm down and get ready for bed. For my daughter, we have established a routine that works like a charm because she's learned that one thing leads to another thing which means sleep.
We all eat dinner together around 6:30 or 7:00. Then she plays for about 1/2 an hour, then I give her a bath and read her a story while I rock her in the chair in her room. I play soft music, then give her another bottle and put her to bed.
You can develop your own routine, but you can see what I mean
