Before your baby came, you might have been an exercise-crazed, tofu-and-kale-eating health nut. But as a new mom, it all gets a little more complicated: Nothing can sap your time or energy like caring for a needy newborn. Read on for some simple tips to keep you on track.

HYDRATE | Make sure you’re drinking plenty of water. Even mild dehydration can make you feel fatigued and headachey. For a quick pick-me-up, drink a glass before reaching for a sweet or caffeinated treat—you might find that water alone does the trick.

SAY YES TO HELP | When friends or family offer to lend a hand, don’t hesitate to take them up on it! If you’re running on a few measly hours of sleep, take a nap. Or if your house looks like a nuclear war zone, settle for a quick, triage clean-up. Alternately, take a bubble bath or snuggle up in bed to watch an episode of your favorite show. Your mental and emotional health are more important than you think.

SNACK WISELY | Chances are, your energy reserves are always low these days. Help yourself out by starting the day with a solid breakfast, then eating small meals every few hours to keep your blood sugar and energy levels stable. Good choices include a banana or toast with peanut butter, Greek yogurt with honey or fruit, trail mix and veggies with hummus.

KEEP IT SIMPLE | You don’t have time now to scrupulously count calories or prepare elaborate meals, so keep it simple. Eat a diet rich in fruit, yogurt, dairy, whole grains, leafy greens and lean protein. (As a bonus, if you’re breastfeeding, you can add about 500 calories to your daily intake!)

DO WHAT YOU CAN | Leisurely, hour-long workouts or intense sweat sessions simply might not be possible for awhile. Take it slow and aim for losing only one or two pounds a week. Make sure to move whenever you can. Take your baby for long afternoon walks—you might think you’re too tired, but once you get outside, you’ll feel better. Have just a few minutes to spare? Do some squats or sit-ups.

MOTHER ’S LITTLE HELPER | On days when you just can’t seem to get away to take a full shower, dry shampoo can be a lifesaver. Spray some on your roots, brush out, and your mane will look (and feel!) as good as new. For under-eye puffiness, soak caffeinated green tea bags in hot water and let cool. Squeeze out excess liquid, then place the bags on your closed eyes for a few minutes.
