Wide awake at night

HarleyKins

My LO is just over 1 month old. She naps well during the day and gets a good 3.5 hour stretch at night before she wakes me up for her first BF round in the middle if the night.

problem is she then is wide awake. I feed her with lights off, don't talk to her, etc. any one have any insight on how to keep her asleep or get her back to sleep quickly? Lately I'm up for 45 minutes after feeding trying. I then wake up my hubby to take over, and he's with her for at least another 30-45 mins trying to get her back to sleep.

 The first 2 weeks were gravy. These last few weeks have been rougher as we now have her in her crib too instead of the PnP bassinet.
