As a new parent you will be learning how to incorporate a baby into your life. The One-Armed Cook is a cookbook that can help you. All of the recipes were prepared one-handed. It is full of tips to help you get back to cooking while you are mothering (or fathering).
My second suggestion is the Flylady. Her website will help you take baby steps to getting your home environment back to where you are comfortable. She will help you declutter your home and keep it neat, clean and organized, even with a baby! The Flylady is comforting and very helpful. I am still taking baby steps myself!
