Trouble sleeping!

Lynzee • Mommy to Ammarie, born on March 3,2016!
Ugh, I've gotten to the point where I have trouble sleeping every night between 2-4. I automatically wake up, because that's when my husband gets home from work, but I can't go back to sleep! 
Last night I slept from 10-12, and was awake until after 5! 
Anyone else going through this already??
