I had a similar problem with my son and I contacted La Leche League for some support. I've included the basics of what they sent to me. I will add that in order for my son to take the bottle, it could not be from me, nor could I be anywhere near him while trying the bottle. Even the sound of my voice disturbed the process. Needless to say, he comfortably transitions from nursing to bottle feeding easily now. Good luck!
Taking one to three oz is within normal for the breastfed baby, provided he is getting enough in a 24-hour period. A lot of mom’s will have 3 or 4 small bottles with 2-4oz each and have the care provider feed the baby more often, rather that 2 or 3 large bottles. This is a great calculator that can help you determine how much your baby needs while you are away. http://www.kellymom.com/bf/pumping/milkcalc.html
There are a few things you guys can try to make this easier for everyone. Sometimes temperature is a sticking point with babies, it’s too hot or too cold. Also determine how they feel he’s hungry, is he on a strict schedule, or fed when he signals he’s hungry? Often when a baby cries, we try feeding them first, this works great at the breast but not so well with a bottle, he may just want to be soothed by sucking.
If he’s just having a hard time taking the bottle in general, there are a few things you could try. You might them try to have them latch him onto the bottle, the same way you do at the breast. If they are putting the nipple in his mouth and he’s not accepting it, this may help. Warming the nipple by running it under warm water might help make it a little more pliable.
If all else fails there are other methods of feeding besides the bottle, you could try using a cup, a soft spout sippy cup, using a syringe (often called finger feeding).
I encourage you to contact your local LLLL, or better yet, go to a LLL meeting if you have one in your area. This concern is frequently discussed at meetings, and you'll have access to great information, and the support and encouragement of other working breastfeeding moms.
