Why are you not napping? If you cosleep with the baby, why are you not breastfeeding in bed during the day? And why baby food in your hair? You do not need baby food - just mash whatever you yourself eat and feed the baby or let the baby squish mashed food. Why are you skipping showers? Put the baby in a carrier and place the carrier on the floor in the bedroom - the baby would love hearing the sound of the water, seeing you with droplets on your skin, and smelling your shower gel and hair products.

I think you are taking this way too seriously because this is the first time. You are describing being on duty. Now is still the time to enjoy. It will only get more challenging with crawling and walking. Now, the baby is still not mobile enough to need vigilance and babyproofing, and yet is social enough already to smile and interact with you. A sweet spot!
