Another Question About Sealing

Question for those who have been sealed to an adopted child after your own sealing as husband and wife: If an adoptive couple has already been sealed prior to adoption, do they need a living ordinance recommend prior to having a newly adopted child sealed to them or do they just need their current reccommends and final adoption decree? Our Temple verbalized that, since my husband and I are already sealed, we just need current recommends and our adoption decree but the confirmation letter they sent said we need a living ordinance recommend. (Do you think this was erroneous? Maybe that is an automatically generated letter that assumes the couple hasn't been sealed yet--that's our Bishop's thought). I've called the temple 4 times and they verbally say we just need recommend and decree (but then they sent me that letter). Help! :) Jennifer
