What you need for a baby when they come home

Well with my first son i thought that i needed everything for a baby i bought him everything the baby bed, bedding, bassinet, changing table etc... After I had him he either slept in the bed with me or the playpen so he had all this stuff he never needed. When you have a baby think practical what do you really need dont buy everything cause that is waht you are supposed to have. Think of the space in your house and where he will sleep and where your going to put the new babies stuff.
