![]() Key Points - Case Study CJoanne is discharged early on day three and comes to see you for a follow-up on day five. The day following discharge her breasts became painful and hard and Rosie is again having difficulty latching on to the breast. Is this normal? What would you suggest Joanne do?
You see Joanne and Rosie again at 10 days. Joanne's breasts have settled and Rosie is feeding well. However, she has been feeding frequently at night and Joanne's husband, Tom, has suggested bringing the baby to bed with them. Joanne has heard that this increases the risk of SIDS. What would you tell her?
Joanne had been on the combined oral contraceptive pill before becoming pregnant. She intends to not use any contraception until she is six months postpartum. Is this a realistic option?
Joanne brings Rosie for immunization at four months. She is concerned about the composition of her milk. Although Rosie had been growing along the 50th percentile, her weight gain has started to slow.
Is there any concern about a slowing of growth around this time?
Joanne asks about introducing solids at this age. How long is breast milk alone adequate for infant growth?

Joanne asks about introducing solids at this age. How long is breast milk alone adequate for infant growth?
A systematic review commissioned by WHO and released in 2001 found that in most circumstances growth and nutrition of infants exclusively breastfed until six months was no different from those who had complementary foods added to their diet at four months1. In addition, there appeared to be an increase in gastrointestinal illness in infants exclusively breastfed for three instead of six months2. A recent United States study also suggests that the incidence of otitis media and respiratory infection is higher when infants are introduced to complementary foods at four months rather than six months3. The WHO, the NHMRC in Australia, the AAP and bodies throughout the world recommend, at a population level, that infants be exclusively breastfed for the first six months of life(4,5,6). Infants who are at risk of becoming deficient in micronutrients such as iron (e.g. premature infants who have limited iron stores) benefit from medicinal supplements rather than the early introduction of solids7.
After six months, breast milk alone may not provide enough energy (especially protein) for adequate growth, and deficiencies in some micronutrients such as iron and zinc may occur. Therefore, nutrient-rich foods with adequate iron content are the most appropriate solid foods at this age. In developed countries, infants aged six to eight months require approximately 130kcal/day from two or three meals of complementary food. This increases to three or four meals plus one or two nutritious snacks to provide 310 kcal/day at nine to 11 months and 580 kcal/day at 12 to 23 months. Although foods at six months tend to be pureed, mashed or semi-solid, by eight months most infants can manage finger food and by 12 months should be eating the same foods as the rest of the family7. If possible, meats should be introduced early as good sources of protein and micronutrients8. Low-fat products are not appropriate for infants or toddlers.
