Pregnancy Insomnia

Courtney
Help! I have a toddler and I'm a SAHM, so being up all night isn't an option. I'd like to save my all nighters for when I have a new baby that needs love all night long. 
What are your tips and tricks for a restful night of sleep!? 
Currently, most nights, I'm sleeping so light and waking every 1-3 hours feeling WIDE awake.
