Crazy, Over Reactive Pregnancy Brain

As of Wednesday, I will have only 35 days remaining until "D-Day" and some panic and impatience is starting to set in. That's only 35 days if she doesn't come early. My mind is racing about what items I could be lacking before the baby arrives. I am having one more shower on Saturday so if I can just be patient until then! We still haven't gotten a baby bath tub or any kind of stuff to wash/bathe her with. While I realize I won't need it immediately, I'm still having some anxiety over these few little things. Once I am past the fact she won't need a bath as soon as she comes home, I start to wonder if she's going to be warm enough. Do I have enough warm clothes for a newborn in November? I have some long-sleeved onesies but not any pants! Hopefully she will do fine with the brand of diapers we have, too. And where are we going to install the car seat? The middle of the backseat or behind the passenger seat? All these little thoughts are looming in the back of my mind and driving me crazy. I hope this isn't foreshadowing to the kind of mother I will be.... obsessive and anxious.
