Methadone???

We just got word that we will be housing a baby boy that is detoxing off methadone in possibly two weeks, so I'm interested in this thread too. We know the biomom and are aware that there were possibly other drugs used with methadone during this preganancy. The baby was born 7 days overdue and was almost 9lbs. Originally, we heard we would probably pick him up in 3-5 days but within 24 hours he was in the NICU and having severe tremors and crying uncontrollably - withdrawals. We aren't allowed in to see him (neither are bio parents/other family) for approximately a two week period. It could be shorter or longer, I guess no one really knows how it will all play out. Very nervous, I've never taken an infant before, all my munchkins are teenagers now!
