Hi Carrie!
I think weekly phone calls to see how things are going would be fine. You want that sw to have you in the forefront of his/her mind. I personally don't understand what is taking so long...you were matched in August? How long did you wait for your other adoption? We only waited one week from telling us we were matched to visiting our daughter. She was home with us within the month (granted she was nine months old and there was no reason to prolong it.)
It sounds like you have already "nested" for your new arrival. Maybe while you wait, you take some time for yourself. Get a pedicure, read a good book, take a bubble bath - or whatever you enjoy. Do you subscribe to Adoptive Families Magazine? I highly recommend it! Is there anything in her records that you need to do research on? Sometimes reading about the things she's gone through or special needs she may have can better prepare you for her arrival. I know for me, reading about preemie development gave me more confidence to parent my little bundle.
In the meantime, keep posting here!

We want to encourage and support you during this time.
Blessings,
