I've been having pregnancy insomnia and i get so bored!!

I lay in bed and play on my phone... but facebook/insta/twitter don't update much in the middle of the night... and once i run out of my 5 candy crush lives then i'm super bored! I've even taken to shopping on Amazon for boring stuff like a carpet pad for under a rug or undershirts for DH.

What do you do when you're wide awake and bored at night?
