My fist did the same thing.......
You may want to take her to the dr to make sure she doesn't have an ear infection or is sick because if you picked her up at 3:30 and she didn't fall alseep until 5:30 that's a long time for one to feel comforted if that is the issue. You may want to purchase a crib riser (Babies R Us or Baby Depot) which helps make breathing a little easier (since you can't use a pillow at this age it is a way to raise their heads a bit to help drain fluids etc.). Also make sure you have a humidifier set up in her room to ease her breathing/congestion also.
If she's not sick, she needs to learn how to fall back to sleep on her own. Start by checking in on her, maybe rubbing her back, putting her music on etc. the first night, next night just talk to her from beside her crib but don't touch her, the night after that move a little further away until by the end of the week you are outside of her room.
OR
go into her room and don't pick her up but just gently touch her telling her it's OK and then walk out of the room and return in 1 min and gradually increase the amt of time you spend out of the room (up to 10 mins). She'll be comforted to know you are still there and are just in the room.
I've tried both of these w/ my children and the first worked the best for us. 9-12 mths is tough but TRUST ME it is key to get them to sleep on their own now vs. later. Some of my friends brought their kids into their beds or slept in their rooms etc. because they gave up quickly at this age and are STILL trying to get them to go to sleep on their own (or out of their beds).
Be sure to put her into her bed while she is still AWAKE.... make bedtime special by starting a routine and be consistent w/ it.
HTH!
