Summarize this article:

Your baby may be more receptive to resuming breastfeeding if you set the right mood. As a general rule, the baby should feel comfortable and soothed.  Do not wait until the baby is very hungry or very tired. Your baby should be relaxed, even to the point of falling asleep. Sit in a rocking chair placed in a dimly lit or dark room. Play soothing music. Keep the area free of distractions for both you and your baby. Try not to stress out each time you sit with your baby to nurse. If your baby senses your stress, he or she will probably become stressed, too. A stressed baby will have very little interest in nursing.  Keep the experience as pleasant as possible—for yourself and for your baby—so that your baby feels as though breastfeeding is a positive thing. Staying calm can also make the process easier for you to bear and may increase your odds of success. Some studies suggest that increasing the amount of physical contact between you and your baby can encourage your baby to accept breastfeeding while also stimulating your milk supply.  Skin-to-skin contact is especially helpful. Spend more time cuddling and stroking your baby. Consider sleeping together or bathing together. Use a sling or a baby carrier to keep your baby close even when you aren't actively nursing. If your baby still refuses to latch on, apply a little milk or formula to the nipple and areola. When your baby tastes it, he or she will identify the area as a source of food and may want to latch on. Before you produce any breastmilk, you can apply formula. After you've succeeded in stimulating some relactation, apply actual breastmilk to the area.

Summary:
Choose the right time and place. Stay calm and patient. Increase touch. Apply milk to the nipple.
