Thirty-one weeks and three days. Feeding is the first thing you'll do for your baby many times a day. Today is a conversation about it, while there's no baby crying and no clock running.
Your baby

Your body
Deciding how you'd like to feed your baby is on the NHS list for this week (NHS). Your body may already be starting: yellow stains in your bra are likely colostrum, an early milk rich in antibodies, which can appear weeks or months before birth (NHS). Milk typically comes in 3 to 5 days after birth (NHS).
The AAP recommends exclusive breastfeeding for about 6 months when possible (Meek & Noble, 2022). Breastfed newborns usually feed 8 to 12 times in 24 hours (AAP); formula-fed babies take about 1 to 2 ounces per feed in the first week (AAP). Plenty of families breastfeed, use formula, or mix the two. Whichever you hope for, it helps to have thought about it before the first night.

The feeding conversation
Time: 20 minutes
Each of you says what you hope feeding will look like, without the other one correcting.
Then say what you'd be OK with if it goes differently. Write both down.
Name who will support you: your partner, your provider, your baby's doctor, a friend who's done it.
If you plan to breastfeed, ask your insurer whether they cover an electric breast pump ordered in advance (AAP).
Make it work:Keep the page with the birth plan. Plans change; having said the backup out loud makes changing easier.
Watch for
Normal
some swelling in your legs, which limiting salty foods may ease.
Call your provider
if leg swelling comes with headaches or high blood pressure, which can be a sign of preeclampsia (MedlinePlus).
Normal
sore ribs, often from your baby kicking.
Call your provider
for severe pain or pain under your ribs, which the NHS says should be checked for pre-eclampsia (NHS).
Normal
an off day with food.
Call your provider
right away for severe nausea and throwing up: if you can't drink for more than 8 hours or eat for more than 24 (CDC).
For you
If you're the partner: your support shapes how feeding goes, whatever form it takes. That means bringing the water, taking the night shift you can take, and backing her choice in front of visitors. Learn the plan as well as she does.
And for both of you: none of this is a test you pass or fail. If cost is part of the worry, the AAP notes that WIC usually supplies a breast pump after birth (AAP).
