Consider reading my long comments about withdrawal in newborns here: http://suboxonetalkzone.com/2010/02/01/withdrawal-in-newborns-lay-off-the-guilt-trip/
If you can taper off the opioids, do so-- slowly, at a rate that you work out with your doc. If you cannot do that, seek the help of an addiction doc. Methadone used to be the 'standard of care' for pregnant opioid addicts, but buprenorphine has a great amount of support over the past few years as causing much milder symptoms for the newborn.
Hi Sweetie. There is nothing that you can do about before you knew you were pregnant, so you cant go so hard on yourself hun because nothing can change that. Its what you do from here on in, now that you know, that counts. God has blessed you with a new lil life so hang in there and see what the o.b says. Sounds like the baby is just fine. But go into things with a positive attitude, as much as you can. I dont know the effects of oxy on fetuses, and its likely they will have to give the baby a lil when he is born so he or she dosnt go into withdrawal, but remember its not your fault and God has given you this special blessing for a reason hun. I have 5 kids as well and my 5th was also a huge surprise. If you would like to chat feel free to message me at any time. Jaxcy
