Most women can make enough milk to feed their baby, because milk works on a supply and demand principle. The more you stimulate the breasts by having your baby suck on them, the more milk you will produce. A few factors can affect your milk production, though, including not drinking enough, being sick, tired or stressed. In some cases, women have glands on only one side, and this can reduce your milk supply. If for some reason your baby is not getting enough milk, talk to your doctor. There are many good supplements out there, and you shouldnâ€™t feel bad about using them. The important thing is getting your baby the right nutrition.
