it's 3am and I'm starving

I am officially 34 weeks along. 6 more to go wow. My frequent trips to the bathroom in the middle of the night are calming down from 8 to about only 3 on average however a new habit is forming - hunger.  Almost every night I wake up around 3am starving and craving carbs.  This probably started about 2 weeks ago.  If I do not physically get up and eat i am unable to fall asleep again. Is it stress, is it baby, is the fact I am eating smaller meals due to heart burn who knows.  I think it all of them combined.  Tonight on the menu is homemade rosemary bread with butter.  

Well almost done my bread so I should be back off to bed.
