Trying to get up at the same time every day would hopefully help your body get into a rhythm. So you can get to sleep earlier, hopefully.
Yep a warm shower, same time each night, trying to get into a pattern. Maybe hubby will have to help with this for a while and take care of bubs while u get ready for bed until ur body lets u get some more sleep!!
Good luck! I hope it gets better soon.
Not sure what to do about the snoring, that's a bummer!
