Originally Answered: Is it possible to go back to breast milk after your baby has been on formula for 2 months?
First of all, ((hugs)) to you. My youngest son had Open heart Surgery back in Sept/06.
Breastmilk is always the optimum form of feeding a baby.....especially a baby with a CHD/illness. No matter your sons age, Breastmilk will benefit him, whether 7 weeks, 7months or 1 year. Breastmilk has known capabilities for increasing immune strength at any age......now, with our CHD babies, infections can be fatal, so ANYTHING that can boost his immune system is worth giving it ALL you've got :)
That being said, YES it is totally possible to re-lactate and nurse again. Most likely, you still have *some* milk left to start out with.
You should contact your local La Leche League for support. They have tons of info on re-lactating....heck, if an adoptive Mom can do, all the more that you can too.
Honestly, it won't be easy....it will take time and patience as well as lots of time spent relaxing and nursing....kinda like the newborn stage again. Same rules apply as in the beginning, you need to have LOTS of direct nursing to start stimulating your breasts to produce. Pumping in between will also help, but nothing is as effective as a REAL baby. Allow your son to pacify himself at the breast if he so chooses. If he seems reluctant to nurse without getting something more out of you (this will change as time goes on and your supply builds back up), look into a Supplemental Nursing System. Its a small sack that hangs around your neck and it attached to a tube that directs formula/pumped milk to your sons mouth as you nurse him. He gets milk AND your breasts get nursed.
There are also some herbs that have been fund to help with production...Domperidone and Fenugreek.
Surf the net, you'll find resources everywhere.
Please feel free to send me an e-mail as I would be more then happy to help you out.
ETA: I too am local to Vancouver. We see Dr. Duncan at Childrens Hospital.
Exclusive pumping *might* work.....how come you couldn't just breastfeed on demand? Maybe you could nurse/pump and bottlefeed?
