Then let your partner feed the baby with the expressed bottle of milk. When you see how long it takes for your baby to drink the bottle, you can have some idea of how much he is getting at each feeding. For example, if he drinks the 4 oz. bottle in fifteen minutes, then you can guess that when he breastfeeds. He is getting somewhere around 8 ounces of breastmilk at each half hour feeding, which is plenty. You must be aware that breastfeeding and bottlefeeding are completely different forms of feeding your baby.
Milk comes out easier in a bottle than a breast.
You also must take into consideration position and attachment. If your baby is not positioned correctly at the breast he may not be able to get the amount of milk that he needs. Please read Positioning and Attachment. Unless you have a medical condition that prevents you from having enough milk, you should have no problem increasing your milk supply and enjoying a remarkable bond with your new baby.
