Sleep at 14w2d!!

Every night for the past week, I've tossed and turned and can't get comfortable!! Anyone have suggestions on sleeping habits?? Also I'm plus size, have a 6 year old and 8 month old to care for so naps are out of the question! My sides get sore from laying on them, my boobs smother me if I lay on my back and I just can't get comfy for the life of me!!
