Does breast size have a link with how much milk it can produce?

As stated above multiple times, It is in fact a supply and demand issue and most moms can produce more if they want. Lactation consultants are a good resource if you need help with low milk supply. Size has no bearing on how much milk you can produce at all, however; the larger your breasts, the more milk you can store and pump in one session. Now that I am breastfeeding I wear a 34JJ maternity bra, so for me on average after a full night sleep (6 -8 hours) I can pump approximately 14 ounces from my left breast and about 11 from my right breast. My friend who was a 36C cup when she was breastfeeding produced approximately the same daily quantity of milk as I do.

Definitley not, size of breasts is no indicaiton what so ever! How much milk you produce is dependent on bub & how well & how often they feed, as your breasts eventually settle to a supply & demand state producing enough milk for your bub. As the others have already said, the more you feed the more you produce.

Like Cher, I also went from an A cup to a C while breast feeding and at every pumping session I would pump between 10 to 14 ounces of milk (when baby skipped a feeding)

No... size does not matter, if your baby nurses a lot then your milk supply will go up, just make sure you eat small snacks in between meals and drink plenty of water! Your body will produce what your baby is drinking. If you are concerned a low supply, then invest in a good breast pump (Medela worked for me) and pump right after baby gets done nursing, that will trigger your body into making more milk.

Only if they have underdeveloped glandular tissue and most women do not have that problem. If they do or thing they might of course get checked out by a doc lactation consultant or midwife and they can recommend or prescribe natural remedies or pharmaceuticals to incourage tissue growth. Goats rue is one of the natural treatments and can be found at through the more milk brand.

The size of your breast has absolutely nothing to do with how much milk you can make. Almost all of breast size is fat. The milk making part of it is tiny until it starts to work.

i was only a A cup before i had my son and i gradually grew to a C cup and then back down to a A cup now(hes 18nths and still bf's 4-5 times a day) I dont think prior breast size really matters,like Celeste said its all how much he/she nurses to tell your body how much milk to produce.I have friends who had d cups to begin with and didnt produce enough for their child and my sister had a NO cup, no boobs and bf!

Overall the answer is no. However, if you develop very little extra size during or after the pregnancy this may indicate your body didnt make enough glands (ducts? not sure the correct word) which could possibly lead to a low supply. However, an A-cup that only grows to a B could also produce more than enough milk.
Celeste is right too. The more you nurse the more your body should get the message to create enough glands to support the supply being requested/ demand.

Nope. Size has nothing to do with it..Supply works on supply and demand. Generally, the more you nurse, the more you will make. The best way to determine if baby is getting enough is by diaper count, depending on age.
