I found that walking did wonders for me. Not only did it help me feel better physically, but mentally as well. Depending on the weather, I would walk for up to 1 hour on my treadmill while watching my favorite (previously recorded) show, or I would walk outside. Another perk is that studies show that walking/exercising will make your delivery easier. More importantly, it will enable your newborn baby to soothe themselves better than they otherwise would have been able to. Best of luck to you!
