Food
I'd like to introduce you to a website that was super amazing when we were brand new parents.
My cousin introduced us and got us set up with this little gem. If you feel like people are offering to bring you a meal, but want to know who is organizing your meals, you simply direct them to your meal train where they can click on a date on the calendar, sign up, and post what they'll be bringing. This avoids lots of stress on you as the new mommy as well as avoiding receiving 20 lasagnas. You can list your favorite foods and any food allergies, along with the best time of evening to bring the meal.
When my cousin set me up, she set it up for every other night which was helpful since people tend to bring more food than needed, so it avoids getting loads of leftovers in your fridge that you'll have to thrown out later.
We didn't realize how helpful meals would be until we were hungry and trying to juggle or new baby while trying to prepare dinner. Trust me, you'll love it.
Clothing
I'm not a big shopper, but I did stumble across a new favorite item of clothing at Old Navy recently.Ordinarily I'm a big camisole wearer. They're perfect for extending a shirt either on top or bottom, but while breastfeeding, it's too much to deal with the extra bra section in the camis while nursing. Here is the perfect alternative that is SO comfortable, reasonably affordable, and most important slim/thin and a perfect replacement for the breastfeeding mama.
I think they're currently $8 when you buy 2 or more.
P.S. Found this pin on 
that was helpful for breastfeeding and would have been nice to read in the beginning: Breastfeeding Timeline
