How to stay energized??


Please help! I have a 14 month at home, I do all the night feedings (2-4 right now with teething and sleep regression) and I work 3 12.5 hour shifts on my feet a week. I do all shopping, cleaning, laundry, kiddo and pet stuff. My husband works a lot. Please tell me what to do to keep energy I'm literally EXHAUSTED!! I currently have my one cup of coffee a day, on my days off I nap for an hour when my kiddo does. Also I'm vegetarian if that matters
