Anyone breast feed and supplement with formula??

while at the hospital, I was nursing but the doctor also had me giving the baby formula to supplement.  I have been trying to nurse..and she is starting to stay on longer just this week but still cries up a storm when finished so I give her formula.  She drinks about 1-2 ounces...I pump and nothing comes out but I know that she is getting milk from me as when she lets go she has a mouthful of it ...my sister says it is not good for them to use both mothers milk and formula as their tummies have a hard time with it adn she HAS been real gassy....what should I do..any suggestions?

My twins were 10 wks premature and had trouble nursing for the first 3 months of their life. In the NICU and at home they were supplemented with high calorie formula (which causes a lot of gas) and breastmilk (both bottle and breast).
They did just fine going back and forth from breast to bottle at each feeding. Yes they had gas, but nearly all formula is going to cause that since all formula is rough on a baby's digestive system.

To me, the health benefits of even some breastmilk supplemented with formula would outweight any worries of a gassy baby. If she's extremely uncomfortable and gassy, she may not be tolerating that type of formula, maybe talk to your pediatrician about switching. 

I tried everything and its brother to produce more milk and it just never got to be more than 1 or 2 ounces so I had to supplement with formula. I used the organic lactose free stuff ... that stopped the gas for my little one completely. Lactose is hard on a lot of babies.

I do both. I had breast surgery a few years ago and I just don't produce enough for him and I also had to supplement soon after he was born because of jaundice issues. (formula clears out jaundice faster than breastmilk) He's never gassy from my milk unless I have beans or something that would cause most people to be gassy. It's always the bottle feeding that causes the issues. Breast milk is easier on their tummy than formula. Also, breast milk has antibodies in it that helps keep them healthy. Our family came down with a stomach bug a few weeks ago and he never got it. My body fighting the illness gave HIM the antibodies that he needed to not get it. I have tried him on every bottle on the market and I still haven't found one that doesn't cause a little gas.
I chose to keep nursing because of the antibody benefit and because its our bonding time. I nurse him primarily when I get home from work, at night before we go to bed and first thing in the morning after he gets up. Nothing beats the way he looks up at me when he's nursing. Some nights when he's fussy, breastfeeding is the only thing that soothes him. Good luck with whatever choice you make..its not an easy decision.

I also have to do both but its worth it

 I didn't make quite enough milk to meets all of my son's needs, especially when he was first born and had a bit of jaundice, so we supplemented all along and he did just fine. No nipple confusion, no trouble handling 2 different food sources. Do what you need to do and things will be OK. They do go through gassy periods, even without formula. You can try a different formula and/or altering your own diet, but even that doesn't always work.

 Also be sure she's no sucking down the "bubbles" at the end of the bottle, try stopping the bottle feeding before the bottle runs dry and that might also help.

I did it with my son...he refused to latch on (or I just wasn't as educated as I could have been) so I pumped and supplemented with formula because I wanted him to have the benefits of breastmilk.  Worked for us.  Maybe a new formula would work better for you both?
