I was on methadone and became pregnant and my baby was born with no detectable withdrawal symptoms. To be safe I chose to breast feed as this is recommended so that the child will receive a small amount of methadone in the milk thus helping the baby to detox. At first it was difficult to breast feed and throughout the first few weeks I did use both breast milk and formula. After a few weeks though my son figured it out and continued to breast feed until he was almost one year old.
I was told that how bad a babie's withdrawal symptoms are depends on how quickly the child metabolizes the methadone. I began my pregnancy at 120mgs and ended at 145mgs. I had been afraid that raising my dose would cause my child to have a worse withdrawal, but the doctors overseeing my care told me that it was important to not expose the fetus to the stress of being sick during pregnancy. I can only say that they seemed to be right because my baby was born healthy, without complication, and with no detectable withdrawal symptoms. Infact the entire birth would have been completely routine had the nurse assigned to my room not treated me like I had aids and put on two pairs of gloves to take my blood pressure! Unfortunately, there is a terrible stigma that comes with being on methadone so make sure you follow your doctors advice and do your research. My son is 4 now and he is a normal, loving, energetic boy. I have read studies that say there is increased risk of behavior problems in babies that are born on methadone, but do not let this freak you out. Remember that behavior problems can never be pinned on one specific source. Most professionals would agree that behavior problems are usually due to a complicated combination of factors such as socio economic status, parenting style, peers, etc. I hope this helps. Congrats!
