My son was born in the Summer in TX. I washed diapers everyday and did baby laundry every three days or so. I changed him on a changing pad and co-slept. When he wasn't napping on our bed or in my lap he would play in his swing or bouncer chair. I bathed him in a simple plastic reclined baby bath. I solely nursed him when he was first born. If we had to go anywhere he had a car seat and the hospital gave us a diaper bag. He needed the next size up in clothes within the first month, but this is all I had and needed at his time of birth.
