When you feed you may wish to try the following suggestions to help make the experience a positive one.
Get yourself comfortable, place pillows behind and around you to support your back. This is aimed at making sure you do not have to move again (to get comfortable) after the baby has latched and possibly shift the baby's mouth off the breast in the middle of a feed.
Support your baby with your hands, or lay them on a pillow in front of you before starting to latch them. This again reduces the chance of them 'slipping off the breast' once latched if you need to move after they are attached. You may wish to wrap them or have skin to skin contact when you feed.
Use the hand that is closest to the breast being fed from to hold the breast (that is if it is the left breast, use the left hand). Make sure your fingers are well back off the areola (brown skin around the nipple) as this is where the baby needs to latch. Place the other hand around the base of the baby's neck and upper back (not on their head). This supports and guides them, without 'pushing them' onto the breast by holding their head and upsetting them.
Chest to chest.
Bring your baby up close to your breast, with their chest against your chest so they are 'facing their food'. It can be difficult for a baby to feed if they are lying 'on their back' and having to turn their head sideways to latch. If they are unwrapped, you can place their lower arm around your waist.
Nose to nipple, chin up!
