3 Months 3 Weeks!!!

I just took a look at my ticker and I noticed that I have officially been waiting for 3 months and 3 weeks and 1 day!!! The wait is such a funny thing. When all the referrals were pouring in I could hardly stand to wait a minute longer... I guess I felt like the referrals were never going to end. But, since things have quieted down and I have some control over my emotions I am feeling good.
There are still a lot of little things that I would like to finish up before my lil' guy gets home. His room, learn more amharic, learn how to cook some basic Ethiopian recipes, etc...
Another positive about the wait is as the time has passed I have found that my kids are more prepared and knowledgeable about what is going to happen and what it will be like when we bring their brother home.
Speaking of room arrangements- those of you who have been in my shoes what did you do? Right now I am contemplating letting all 4 of my children share a room by re-modeling 2 rooms into 1 giant room with two sets of bunk beds. I have 3 kids rooms upstairs. One belonged to my boys, another was Belle's and the third is a guest room. But, we have had a hard time getting Belle to sleep in her own room so as of late she has been sleeping on a crib mattress on the floor in her brothers room. Ha... laugh if you will but this arrangement has been great. They read books to each other and then lights out and we get more personal time than we have in a loonng time- WooHoo!!!
My other thoughts are letting Belle and the new lil' guy share a room, keep the boys together and then I would still have my guest bedroom. ugh... I suppose there are a lot of options. I could also make the big room and just put the boys in it... but I feel bad for Belle. While they are all young I feel like I should keep them all together regardless of gender, and as they get older we can begin to separate them again. See I should be thankful that I have this time, I have a lot of thinking to do ;)
FYI I am assuming that for some time our lil' guy will most likely be in our room. But, I would like his bed set up so he has a place at home when he arrives even if it does not get used for awhile. So, what are your plans or do you have any suggestions for me?
