Set up a bedtime routine and stick to it.
Time in the swing (30 mins)
Bedtime (In crib)
At first she WILL cry and you NEED to leave her there. Set a timer for 10-15 mins and do not go in till the alarm goes off. She will probably be asleep before then.
I know this sounds terrible but it does work and it is more traumatic for you than the baby. I did this with both my kids and it worked like a charm
