Bad timing?

I've got myself wondering lately if we chose to start the adoption process at the wrong time of year...wondering if because of all these holidays if we're going to have to get things redone because things won't happen within the time schedule for them?  I'm worried about the home study taking so long, we had the initial meeting on Oct 5th, the social worker said she would write up the study and when we get the clearances in, she would plug the info into the study.  I'm not sure she's done anything with our home study report because she does not seem active in our case.  It makes me worried and at times I feel so angry as to why things are taking SO long.  I believe in my heart that we have made the right decisions, but it's the waiting that is making me second guess everything. 
I finished putting the nursery together, the furniture is so cute!  I can't wait to get a mattress so we can make the bed up.  Should I wash the bedding now or wait until we get the call?  If I wash it now, but don't meet our baby for another 6 months, would I have to rewash it?  What about the handful of onsies that we have?  Oh, and what product is safe to clean the furniture?  I wouldn't think pledge would be safe if the child decides to start gnawing on the edge of the crib?  Hubby thinks it's okay, but I'm a bit concerned.  I'll take a picture today, then another one when we get the mattress and the bed is made up.
I've also decided to wait on hanging up the pictures that go with the bedding set because after we bring the baby home, I want to get the letters that make the name and put it in between the two pictures.  I think that would look nice.  We are also going to use the top of the dresser as the changing table.  We still need to buy:  mattress, changing pad, night stand, and rocking chair.  Plus, all the baby basics we need like bath stuff, clothes, diapers, wipes and so on and so on...just don't want to buy all that now because what if we don't meet our baby for a few months?  Would the stuff go bad?  Not really wanting to buy clothes because we could adopt a baby up to a year old.
Prayer has been a big part of my nightly routine lately, I've been praying every night for our expectant parents, hoping they are pregnant right now, and praying for peace and patience as we wait.  There have been many families on a discussion board that I've been reading that have had failed placements or the courts have them on hold in another country.  I've been praying for these families that they will be united with their children soon.  Then I like to give thanks to the Lord for all the love he has given and shown.  (We really need to find a church here, I feel so lost and love to sit in the pew and talk to Him).
Sorry for the vent...feeling so sad and lost today
