Do any laundry that needs to be done. Go grocery shopping and make sure you've got plenty of supplies for the baby. You'll still be doing a lot of work around the house. But it sure is fun looking at the small child before you and thinking about what went into creating this tiny life. Do a lot of cooking.
Prepared foods are fine.
Bake a lasagna on Sunday night and it will help feed you and her for a few days. Pasta salad is another good choice. Look for healthy food choices that will keep you well-fed but don't require a lot of time or effort to prepare. The baby will also be sleeping quite a bit. It's recommended that you move the crib into your bedroom so you can keep an eye on them both.
