F.R.
at night you have to keep the atmosphere different. no tv, very dim lights, very little noise. don't try to play or talk much. keep the night stuff strictly business. Get her up, start the feeding, stop half-way, burp, do a diaper change. Finish the feeding, burp again, swaddle and lay her back down. You can sit and rock her a little before laying her back down, but with a couple of mine the rocking would keep them awake instead of lull them to sleep. (I have 4)
It gets easier with time and routine. If you do the same things every night, she'll catch on that mommy's not nearly as fun at night than she is during the day. May as well sleep.
Congrats on your new baby!
Oh... and a white noise machine is the best invention EVER!
