I'm 3 days postpartum, my nipples are cr

Call your local emergency number now if any red flag below shows up, and call your lactation consultant line today, before the next feed, because cracks three days after birth are usually a latch or position problem rather than something to push through.

1. What you've tried, and what to do instead

You've been pushing through painful latches. Pain at every feed plus cracks is the one thing NHS advice says to get help on early, because cracked skin raises your chance of a breast infection. Two changes instead of endurance:

• The call itself is the highest-value thing on the list. A latch cannot be fixed by reading; it is fixed by someone watching. NHS: putting up with the pain "could make pain or discomfort worse, so it's important to get help from your midwife, health visitor or breastfeeding specialist as soon as you can."
• Check the latch yourself at the next feed, in 60 seconds. After the baby is on, the nipple should sit deep against the soft palate at the back of the mouth. If your nipple is flattened, wedged or white when it comes off, the latch is not right — that is the sign NHS names. Take the baby off and re-latch rather than finishing a bad one.
• Let the baby finish one breast before switching, and offer both breasts each feed, alternating which one you start with. Frequent, responsive feeding and skin-to-skin are what build supply.
• Air and dry, then protect. Change breast pads at every feed, and use pads without plastic backing if you have them. Wear a well-fitting bra with no underwire. If you're using a nipple cream, keep using it as the label or your clinician instructed — this answer doesn't change any medicine.
• After a feed, dab a few drops of your own expressed milk onto the nipple and let it air-dry. NHS names this and also silver nipple cups between feeds if you have one.
• Your pump is a rest, not a replacement. If a feed is too painful, pump that side to take the pressure off, then latch again. Pumped milk can go to the baby or the bottle you're already using.

How you'll know your milk has come in (and this is the honest version)

You often feel it before you see it: breasts go hard, tight and heavy, and leaking starts. That fullness is normal in the early days while your supply matches your baby's needs. It's also a reason feeds can't be skipped or delayed right now.

The real "enough is happening" signs are on the baby side, not the breast side: baby is settled after feeds, and baby is producing wet nappies. NHS: "It can take a little while before you feel confident that your baby is getting what they need." If you're unsure, that's exactly what the consultant call is for — a weighted nappy check is their job, not something to guess at.

Feeding the baby your own milk *and* formula is not a failure and does not stop your milk coming in. Keep following the exact amount and preparation on your formula tin, measured with the scoop and water it specifies — that's the one place never to improvise, and no one should be adjusting your baby's formula amount without your baby's own clinician. If you want to reduce formula, that's a decision to make *with* the consultant or your baby's clinician, based on your baby's weight and wet nappies — not a number decided at 3am.

2. Constraints and the avoid list

• No nipple shields or breast shells — NHS says these can affect how your baby attaches. Worth knowing before someone buys them.
• Don't stop breastfeeding out of pain, and don't push through a latch you know is wrong.
• Don't switch, dilute, or "make up" formula, and don't add anything to the bottle.
• No powders, herbal capsules, fenugreek-type supplements, or anything bought online to boost supply — bring them to the consultant instead, because they can interact with what you or the baby are taking.
• No medicine, cream or supplement changes based on this answer — including anything a relative or neighbour offers.
• No leftover antibiotics from a previous course if you get a hot, red breast — that's a clinician's call, and it needs to happen the same day.
• Keep the phone script short; the caregiver juggling school week gets the food-and-school job, not the 3am one.

A script you can screenshot and send to the caregiver tonight

> "Feed the baby however she's set up — I'll pump if she's too sore. If the baby is crying hard for more than 10 minutes, get me, don't troubleshoot it. Formula goes exactly by the tin, scoop and water, nothing added. If her breasts get hot and red or I start shivering, wake me or call the line. If I seem confused or not myself, call someone, don't leave me alone with her."

3. Red flags — when to stop DIY and get clinical or urgent help

Today, with the lactation consultant / your maternity unit or midwife (this is the current level, and it is not optional just because it hurts less today):

• Nipples cracked or bleeding, or pain at every feed — NHS says get help as soon as you can, and that cracks raise the risk of infection.
• A tender lump in the breast, or a hot, red, painful patch of breast.
• Pain that isn't settling once the latch is corrected, or itching, or the breast looking different.
• Any worry that the baby isn't getting enough milk.
• If you're no better within 12–24 hours, or you feel worse, contact your GP or urgent line — you may need antibiotics. (NHS.)

Go now, do not wait — call your local emergency number and say the words *"I gave birth three days ago"*:

• Fever, shivering/chills, or feeling too weak to get out of bed, especially with belly pain or an offensive-smelling discharge. After birth, sometimes the only sign of infection is a low-grade fever — don't wait for a high one.
• Vaginal bleeding that is heavy or getting heavier rather than settling, or faintness, dizziness or a pounding heart.
• One-sided calf pain, redness or swelling; chest pain; or fast or difficult breathing. New breathlessness after birth is not just "new baby tired".
• Severe headache with blurred or flashing vision, pain high in the belly, or sudden puffiness of face or hands — this can start *after* the birth.
• Not yourself, losing touch with reality, frightening thoughts, or any thought of harming yourself or the baby — do not leave her alone; arrange help by phone rather than going out. Don't let anyone call this ordinary tiredness.
• The baby: not feeding, fewer wet nappies, floppy, or a fever in a baby this young.

What success looks like in 24 hours — not a promise, a target

By tomorrow evening, a realistic win is: a feed that hurt less than today's worst one rather than zero pain; your nipples looking sealed or scabbed rather than wet-cracked; one feed where you didn't have to re-latch three times; you having spoken to the consultant and got a plan; and baby settled with wet nappies. Supply rising is a days-to-weeks story, not a 24-hour one — treat day 3 as too early to judge it. If any red flag above shows up, success is getting seen, not pushing through.

Not covered by this answer / 未覆盖 / cannot confirm: your baby's exact formula amount and how much to reduce it, any medicine or cream change, whether your nipples have an infection, and which local number to call. None of those can be worked out without seeing the feed and the baby — that is the consultant's and your baby's clinician's call, and I will not guess a number. If you tell me your country or city, I can point you at the right official door.
