Day-5 weight loss and breastfeeding pain in a first-time parent
A 27-year-old first-time mother is visited at home on day 5 after a spontaneous vaginal birth. Her baby was born at 39+2 weeks, weighs 3.2 kg today and has lost 9.6% of birth weight. She is breastfeeding 8–9 times in 24 hours, but each feed is painful; both nipples are cracked and she is using a nipple shield. The baby is sleepy at the breast, has had six wet nappies and three yellow stools in the last 24 hours, and looks mildly jaundiced to the abdomen. Maternal temperature is 37.4°C, pulse 88, and blood pressure 118/72. She is tearful, has had little sleep, and says her partner has returned to work and her own mother lives overseas. She asks whether she should stop breastfeeding and give formula. She has no family violence concerns and no thoughts of harming herself or the baby.
1. Assess the breastfeeding and newborn findings, and outline your immediate management.

A 9.6% weight loss at day 5 is significant and close to the 10% threshold that usually triggers closer review. Six wet nappies and three yellow stools are reassuring, but the sleepy baby, cracked nipples, nipple shield use and painful feeds suggest ineffective milk transfer and maternal risk of nipple trauma or mastitis. I would observe a full feed: positioning, attachment, suck-swallow pattern, breast fullness, and whether the shield is needed or is masking a latch problem. I would check the baby’s temperature, tone, hydration and jaundice, and ask about feeding duration and whether the breasts feel emptied.
Immediately, I would help her improve attachment and try different positions, hand-express or pump after feeds to protect supply, and use expressed milk for top-ups if the baby is not transferring milk effectively. I would refer to a lactation consultant and arrange a GP or neonatal review within 24 hours for weight and jaundice assessment. I would give clear safety-net advice: fewer wet nappies, worsening jaundice, fever, poor feeding or maternal breast pain and fever require urgent review. I would also screen for postnatal depression and exhaustion and document the assessment and plan.
2. How would you discuss her question about stopping breastfeeding and formula feeding, and what follow-up would you arrange?

I would normalise the question and avoid sounding judgemental. I would say that formula is a legitimate option and that her wellbeing matters, but that painful feeding is usually fixable and she does not have to decide permanently today. I would explain the benefits of continuing breast milk where possible, the risks of ongoing nipple damage if nothing changes, and what formula top-ups would mean for supply and her feeding goals. I would ask what she wants, rather than assume.
If she wants to continue, I would put a practical plan in place: skilled latch support, pain management, expressing, and a review in 24–48 hours. If she wants to stop or mix-feed, I would support safe formula preparation, responsive bottle-feeding, and advice about engorgement and supply reduction. I would also discuss her sleep, mood and practical support, and ask about her partner and whānau.
Follow-up would include a home visit or phone contact within 24 hours, lactation referral, GP review for the baby’s weight and jaundice, and a clear pathway back to maternity care if concerned. I would document her decision, the information given, the safety net, and referrals made.
