From my own experience I want to share what I learned about getting your baby latched/posotioned correctly. NEVER push your baby's head into your breast.

Your hand should support the base of your baby's head and your fingers shouldn't touch your baby's cheeks or press on the back of your baby's head. This is very important since babies have a reflex that causes them to push back, which can mess up your latch and if continued cause the baby distress which could lead baby to have an aversion to nursing (see part of my experiences with this HERE).
La Leche League's article on latch/positioning,
The Mother-Baby Dance: Positioning and Latch-On says:
"It is important not to touch the top or back of the newborn's head because it is very sensitive after birth. When the head is touched the baby may have a tendency to pull back from mother's breast rather than move in toward the nipple. This may be the reason why some mothers have trouble getting the baby to latch on. They try to force the baby onto the breast by firmly holding the back of baby's head which causes baby to arch away from mother's breast."
I wish I would have known this at the beginning, as it could have possibly saved my baby girl and me months of problems and heartache. Good luck to you all!
