Here are some other suggestions to help you avoid over-feeding your baby during her first year of life:
Don’t automatically give her more. Resist the temptation to keep feeding her until she refuses to take any more. Remind yourself that she doesn’t have to be “full” all the time.
There is a difference between having enough to eat and being full. She doesn’t have to be so stuffed she cannot swallow another drop.
As the birth of my third child approaches, breastfeeding anxiety is setting in. It’s not that I had problems feeding my two boys. On the 
contrary, my milk supply was ample and both of them were sucking away in no time.
What’s haunting me is the latter part of the love-hate relationship I have with nursing: leaking breasts the size of watermelons; feeling like I belong on a meadow among the cows; constantly smelling of breast milk; horrible cotton pads stuffed into bras that look like something from Grandma’s underwear drawer; and being the only one who can feed the baby in the middle of the night.
