Drink More Water!
When pregnant and breast feeding you need 60+ ounces of liquid a day. You will hear this so much that water will begin to not sound good anymore. Try making yourself a spritzer when you have had enough of the plain tap version. Add a splash of juice to sparkling water for a refreshing, hydrating change.
Always carry water with you when you are on-the-go so you can sip throughout the day (using an aluminum or stainless steel reusable water bottle is best for your health and that of the environment – brands such as SIGG or Klean Kanteen are great options).
Fitness Tip: Train for a "child friendly race/walk" with your child. Set periodic, attainable, goals (distance, time, exploring new terrain like a hilly park) to keep it interesting and challenging.
