Need help!!

For the last two nights I have not got much sleep. Jena wants to be awake during the 2 am to 6 am hours and then sleeps hard in the morning. She has alittle of awake time and tummy time during the day but not enough to keep her asleep during the night. If anyone out there has any help tips for me I would greatly appreciate it. My eye balls are hurting cause I haven't had much sleep. It's about 5:40 pm now and I'm going to give her a bath and try to stir her up. But please help me if you can.
