There are lots of different positions for breastfeeding. You just need to check the following:
Are your baby's head and body in a straight line?
If not, your baby might not be able to swallow comfortably.
Are you holding your baby close to you?
Try to support his back, shoulders and neck. He should be able to tilt his head back easily. And he shouldn't have to reach out to feed.
Is your baby's nose opposite your nipple?
Your baby needs to get a big mouthful of breast from underneath the nipple. Placing your baby with his nose level with your nipple will allow him to reach up and attach to the breast well.
Are you comfortable?
It's OK to change your position slightly once your baby is attached to your breast.
Breastfeeding is the healthiest way to feed your baby. If you decide not to breastfeed or to stop breastfeeding, it is possible to restart but it will be difficult. Giving formula milk to a breastfed baby will reduce your breastmilk supply. You do not need to eat any special foods when breastfeeding but it is a good idea for you, just like everyone else, to eat a healthy diet.
