Rest up. Your body needs energy to make milk. Take a nap when your baby is napping, or lie down and read a book. Skip evening TV and go to bed as early as possible.
Eat and drink plenty. It can be easy to skip meals while focusing all of your attention on your baby. Make sure to drink plenty of fluids and eat three nutritious meals a day, with healthy snacks in between.
Nurse frequently. Forget trying to keep baby on a “schedule” and nurse as frequently as your baby would like. That may be every 2 hrs or it may be every 45 minutes. Frequent nipple stimulation will lead to greater milk supply.
