getting nervous

we don't have anything for baby .. I know we have 3 months left but this is baby #4 and you never know when he'll be ready to come! my mother in law is supposed to throw me a baby shower but she's also trying to give me all this old stuff she has and I want a new car seat not an old one, I want a bassinet and I don't want the baby sleeping in a pack n play. ah this is getting stressful
