🥼 Breastfeeding & Newborn Feeding

You cannot measure a breastfeed, so you judge it by output. Wet diapers, latch, and why mastitis is not a reason to stop.

⭐ Judge it by output, not intake

A shallow latch beside a deep one - the shallow taking only the nipple, the deep taking a good mouthful of areola with the lips flanged out and the chin touching - and the signs a feed is working, judged by output.
Nipple pain almost always means a shallow latch, and the fix is to re-latch rather than to stop. Swipe it sideways if it is cut off, or tap to open it full size.

Nobody can measure how much a breastfed baby took. So the assessment is what comes out and what the scale says.

Sign it is workingDetail
Wet diapers6–8 a day once the milk is in (day 4 onward)
Stools3–4 a day; meconium → green → yellow and seedy
WeightRegains birth weight by 2 weeks
Feeding8–12 times in 24 hours in the early weeks
During the feedAudible swallowing; baby releases the breast, content

Up to 10% weight loss in the first days is normal and expected. It is failure to regain by two weeks that signals a problem.

🧠 Latch — where most problems start

A good latch takes the nipple AND a good mouthful of areola, with the lips flanged outward, chin touching the breast and nose free.

Nipple pain almost always means a shallow latch. The fix is to re-latch, not to stop feeding.

Never pull the baby off the breast. Break the suction first with a clean finger in the corner of the mouth, or the nipple tears.

ProblemWhat helps
EngorgementFeed more often. Warm compress or shower before to let down; cold pack after for swelling
Sore, cracked nipplesFix the latch; express a little milk onto the nipple and air dry
MastitisFever, flu-like aching, a red wedge on one breast. KEEP FEEDING + antibiotics + rest
Flat or inverted nipplesBreast shells, hand expression before latching

Mastitis is not a reason to stop breastfeeding. Emptying the breast is part of the treatment - stopping makes it worse and risks an abscess.

Offer the unaffected breast first, then the affected one. The milk is safe for the baby.

🍼 Storage, formula and safety

Storing expressed milk

  • Refrigerated: about 4 days
  • Freezer: about 6 months (deep freeze longer)
  • Store in sealed containers or milk bags, in small portions
  • Thaw in the fridge or under warm running water
  • Swirl to mix — separation is normal

Never microwave breast milk or formula. It creates hot spots that burn, and microwaving destroys immune components in breast milk.

🥛 What breast milk is low in

Vitamin D — supplementation is recommended for breastfed infants.
Iron stores run down around 6 months — which is why iron-fortified cereal is the usual first solid.

Breast milk provides immunoglobulins the baby cannot make yet, which formula cannot replicate.

🚨 Absolute feeding rules for the first year

  • No honey before 12 months - infant botulism
  • No cow's milk before 12 months
  • No solids before about 4–6 months; start with iron-fortified cereal
  • One new food every 4–7 days so reactions can be identified
  • Never prop the bottle — choking and ear infections
  • Discard formula left more than 1 hour after a feed begins

🎯 NCLEX traps

  • 6–8 wet diapers is the answer to “how do I know she is getting enough?”
  • Keep feeding through mastitis
  • Warm before, cold after for engorgement
  • Break suction before removing the baby
  • No honey, no cow’s milk, no microwaving
  • Breastfeeding is not reliable contraception
